The origin of this patch is the breaking of am335x-hs boot

HS boards have less SRAM for SPL and so this commit increased memory usage beyond am335x limit.
This commit added 10 driver binding pass and am335x boot only if one pass is done.
SPL try to do more than one pass due to eth_cpsw failing.

armv8: always use current exception level for TCR_ELx access
Currently get_tcr() takes an "el" parameter, to select the proper
version of the TCR_ELx system register.
This is problematic in case of the Apple M1, since it runs with
HCR_EL2.E2H fixed to 1, so TCR_EL2 is actually using the TCR_EL1 layout,
and we get the wrong version.
For U-Boot's purposes the only sensible choice here is the current
exception level, and indeed most callers treat it like that, so let's
remove that parameter and read the current EL inside the function.
This allows us to check for the E2H bit, and pretend it's EL1 in this
case.
There are two callers which don't care about the EL, and they pass 0,
which looks wrong, but is irrelevant in these two cases, since we don't
use the return value there. So the change cannot affect those two.

net: Check for the minimum IP fragmented datagram size
Nicolas Bidron and Nicolas Guigo reported the two bugs below:
"
----------BUG 1----------
In compiled versions of U-Boot that define CONFIG_IP_DEFRAG, a value of
`ip->ip_len` (IP packet header's Total Length) higher than `IP_HDR_SIZE`
and strictly lower than `IP_HDR_SIZE+8` will lead to a value for `len`
comprised between `0` and `7`. This will ultimately result in a
truncated division by `8` resulting value of `0` forcing the hole
metadata and fragment to point to the same location. The subsequent
memcopy will overwrite the hole metadata with the fragment data. Through
a second fragment, this can be exploited to write to an arbitrary offset
controlled by that overwritten hole metadata value.
This bug is only exploitable locally as it requires crafting two packets
the first of which would most likely be dropped through routing due to
its unexpectedly low Total Length. However, this bug can potentially be
exploited to root linux based embedded devices locally.
/* payload starts after IP header, this fragment is in there */
payload = (struct hole *)(pkt_buff + IP_HDR_SIZE);
offset8 = (ip_off & IP_OFFS);
thisfrag = payload + offset8;
start = offset8 * 8;
len = ntohs(ip->ip_len) - IP_HDR_SIZE;
```
The last line of the previous excerpt from `u-boot/net/net.c` shows how
the attacker can control the value of `len` to be strictly lower than
`8` by issuing a packet with `ip_len` between `21` and `27`
(`IP_HDR_SIZE` has a value of `20`).
Also note that `offset8` here is `0` which leads to `thisfrag = payload`.
```C
} else if (h >= thisfrag) {
/* overlaps with initial part of the hole: move this hole */
newh = thisfrag + (len / 8);
*newh = *h;
h = newh;
if (h->next_hole)
payload[h->next_hole].prev_hole = (h - payload);
if (h->prev_hole)
payload[h->prev_hole].next_hole = (h - payload);
else
first_hole = (h - payload);
} else {
```
Lower down the same function, execution reaches the above code path.
Here, `len / 8` evaluates to `0` leading to `newh = thisfrag`. Also note
that `first_hole` here is `0` since `h` and `payload` point to the same
location.
```C
/* finally copy this fragment and possibly return whole packet */
memcpy((uchar *)thisfrag, indata + IP_HDR_SIZE, len);
```
Finally, in the above excerpt the `memcpy` overwrites the hole metadata
since `thisfrag` and `h` both point to the same location. The hole
metadata is effectively overwritten with arbitrary data from the
fragmented IP packet data. If `len` was crafted to be `6`, `last_byte`,
`next_hole`, and `prev_hole` of the `first_hole` can be controlled by
the attacker.
Finally the arbitrary offset write occurs through a second fragment that
only needs to be crafted to write data in the hole pointed to by the
previously controlled hole metadata (`next_hole`) from the first packet.
### Recommendation
Handle cases where `len` is strictly lower than 8 by preventing the
overwrite of the hole metadata during the memcpy of the fragment. This
could be achieved by either:
* Moving the location where the hole metadata is stored when `len` is
lower than `8`.
* Or outright rejecting fragmented IP datagram with a Total Length
(`ip_len`) lower than 28 bytes which is the minimum valid fragmented IP
datagram size (as defined as the minimum fragment of 8 octets in the IP
Specification Document:
[RFC791](https://datatracker.ietf.org/doc/html/rfc791) page 25).
----------BUG 2----------
In compiled versions of U-Boot that define CONFIG_IP_DEFRAG, a value of
`ip->ip_len` (IP packet header's Total Length) lower than `IP_HDR_SIZE`
will lead to a negative value for `len` which will ultimately result in
a buffer overflow during the subsequent `memcpy` that uses `len` as it's
`count` parameter.
This bug is only exploitable on local ethernet as it requires crafting
an invalid packet to include an unexpected `ip_len` value in the IP UDP
header that's lower than the minimum accepted Total Length of a packet
(21 as defined in the IP Specification Document:
[RFC791](https://datatracker.ietf.org/doc/html/rfc791)). Such packet
would in all likelihood be dropped while being routed to its final
destination through most routing equipment and as such requires the
attacker to be in a local position in order to be exploited.
/* payload starts after IP header, this fragment is in there */
payload = (struct hole *)(pkt_buff + IP_HDR_SIZE);
offset8 = (ip_off & IP_OFFS);
thisfrag = payload + offset8;
start = offset8 * 8;
len = ntohs(ip->ip_len) - IP_HDR_SIZE;
```
The last line of the previous excerpt from `u-boot/net/net.c` shows
where the underflow to a negative `len` value occurs if `ip_len` is set
to a value strictly lower than 20 (`IP_HDR_SIZE` being 20). Also note
that in the above excerpt the `pkt_buff` buffer has a size of
`CONFIG_NET_MAXDEFRAG` which defaults to 16 KB but can range from 1KB to
64 KB depending on configurations.
```C
/* finally copy this fragment and possibly return whole packet */
memcpy((uchar *)thisfrag, indata + IP_HDR_SIZE, len);
```
In the above excerpt the `memcpy` overflows the destination by
attempting to make a copy of nearly 4 gigabytes in a buffer that's
designed to hold `CONFIG_NET_MAXDEFRAG` bytes at most which leads to a DoS.
### Recommendation
Stop processing of the packet if `ip_len` is lower than 21 (as defined
by the minimum length of a data carrying datagram in the IP
Specification Document:
[RFC791](https://datatracker.ietf.org/doc/html/rfc791) page 34)."
Add a check for ip_len lesser than 28 and stop processing the packet
in this case.
Such a check covers the two reported bugs.

armv8: Fix TCR 64-bit writes
The AArch64 TCR_ELx register is a 64-bit register, and many newer
architecture features use bits in the upper half. So far U-Boot was
igorant of those bits, trying to leave them alone.
However, in an effort to set bit 31 to 1, it failed doing so, because
the compiler sign-extended "1 << 31", so that all bits[63:31] got set.
Older ARMv8.0 cores don't define anything dangerous up there, but newer
architecture revisions do, and setting all those bits will end badly:
=================
$ qemu-system-aarch64 -cpu max ....
U-Boot 2022.07-rc1 (May 09 2022 - 15:21:00 +0100)
DRAM: 1.5 GiB
================= (hangs here)
Defining TCR_ELx_RSVD to "1U << 31" avoids the sign-extension, so all
upper bits stay at a safe 0 value. This means no more surprises when
U-Boot runs on a more capable CPU core.

ubifs: Fix lockup/crash when reading files
Commit b1a14f8a1c2e ("UBIFS: Change ubifsload to not read beyond the
requested size") added optimization to do not read more bytes than it is
really needed. But this commit introduced incorrect handling of the hole at
the end of file. This logic cause U-Boot to crash or lockup when trying to
read from the ubifs filesystem.
When read_block() call returns -ENOENT error (not an error, but the hole)
then dn-> structure is not filled and contain garbage. So using of dn->size
for memcpy() argument cause that U-Boot tries to copy unspecified amount of
bytes from possible unmapped memory. Which randomly cause lockup of P2020
CPU.
Fix this issue by copying UBIFS_BLOCK_SIZE bytes from read buffer when
dn->size is not available. UBIFS_BLOCK_SIZE is the size of the buffer
itself and read_block() fills buffer by zeros when it returns -ENOENT.
This patch fixes ubifsload on P2020.

efi_loader: bootmgr: fix a problem in loading an image from a short-path
Booting from a short-form device path which starts with the first element

in efi_load_image_from_path() will return NULL.
For instance,

With this patch applied, all the media devices with simple file system
protocol are enumerated and the boot manager attempts to boot temporarily
generated device paths one-by-one.
This new implementation is still a bit incompatible with the UEFI
specification in terms of:
* not creating real boot options
* not try
"If a device does not support the EFI_SIMPLE_FILE_SYSTEM_PROTOCOL, but
supports the EFI_BLOCK_IO_PROTOCOL protocol, then the EFI Boot Service
ConnectController must be called for this device with DriverImageHandle
and RemainingDevicePath set to NULL and the Recursive flag is set to TRUE."
(See section 3.1.2 "Load Option Processing".)
