vexpress64: juno: add alternate kernel and device tree filenames
The latest Juno firmware stores the files in NOR flash as "norkern" for
kernel binary, "board.dtb" for the device tree binary.
The "old" firmware used the name "Image" for the kernel binary and
"juno" for the device tree binary.
Rather than just change the default U-Boot configuration to use the new
names, breaking users with the old firmware, attempt to load the default
filename first. If that fails, attempt to load the alternate filename.
I've echo'd that we are loading the alternate file to counter the
output from "afs load" shown if the first load attempt fails. For
example, I see output like this on my Juno board when it's configured
the with the "old" firmware:
image "norkern" not found in flash

sunxi: Fix USB regulators in Linksprite_pcDuino_defconfig
The pcDuino1 board unconditionally provides 5V to USB host
receptacles. The pcDuino2 board has a voltage regulator,
controlled by the PD2 pin which is pulled-up by default
(so that the USB power is also enabled by default).
Not specifying pins for enabling USB power in the defconfig
means that the PH3 and PH6 pins are driven high by default.
The PH6 pin is available on the Arduino-compatible expansion
header and touching it is not nice (this may be even dangerous,
depending on what kind of role is assigned to this particular
pin by various Arduino shields).
This patch explicitly configures the USB VBUS pins to "",
which means that no pins should be touched. The patch has
been tested on a pcDuino2 board and USB still works.

dm: core: Don't use pinctrl for the root device
Currently when driver model starts up it finds the root uclass and the
pinctrl uclass. This is because even the root node handles pinctrl
processing.
But this is not useful. The root node is not a real hardware device so
cannot require any particular pinmux settings. Also it means that the
memory leak tests fails, since they end up freeing more memory than
they allocate: the marker it set after the root device and pinctrl
uclass are allocated, and later once the pinctrl uclass is freed the memory
used by driver model is less than when the marker was set.
If a platform needs 'core' pin mulitplex settings it can do this with
a driver that is probed on start-up. It would be an abuse of the root node
to use this for pinctrl.
To avoid this problem, only process pinctrl settings for non-root nodes.

rockchip: Reconfigure the malloc based to point to system memory
When malloc_base initially gets setup in the SPL it is based on the
current (early) stack pointer, which for rockchip is pointing into SRAM.
This means simple memory allocations happen in SRAM space, which is
somewhat unfortunate. Specifically a bounce buffer for the mmc allocated
in SRAM space seems to cause the mmc engine to stall/fail causing
timeouts and a failure to load the main u-boot image.
To resolve this, reconfigure the malloc_base to start at the relocated
stack pointer after DRAM has been setup.
For reference, things did work fine on rockchip before 596380db was
merged to fix memalign_simple due to a combination of rockchip SDRAM
starting at address 0 and the dw_mmc driver not checking errors from
bounce_buffer_start. As a result, when a bounce buffer needed to be
allocated mem_align simple would fail and return NULL. The mmc driver
ignored the error and happily continued with the bounce buffer address
being set to 0, which just happened to work fine..

fdt: fix fdtdec_get_addr_size not to require any size cells
fdtdec_get_addr_size() may be used in two cases:
a) With sizep supplied, in which case both an address and a size are
parsed from DT. In this case, the DT property must be large enough to
contain both values.
b) With sizep NULL, in which case only an address is parsed from DT.
In this case, the DT property only need be large enough to contain this
address value. Commit 02464e386bb5 "fdt: add new fdt address parsing
functions" broke this relaxed checking, and required the DT property to
contain both an address and a size value in all cases.
Fix fdtdec_get_addr_size() to vary ns based on whether the size value
is being parsed from the DT or not. This is safe since the function only
parses the first entry in the property, so the overall value of (na + ns)
need not be accurate, since it is never used to step through the property
data to find other entries. Besides, this fixed behaviour essentially
matches the original behaviour before the patch this patch fixes. (The
original code validated that the property was exactly the length of
either na or (na + ns), whereas the current code only validates that the
property is at least that long. For non-failure cases, the two behaviours
are identical).

target for sunxi boards.

of other (usable) boot devices - or to be able to override them,
deviating from the standard boot sequence. To achieve this, the "fel"
boot target gets the highest priority, but won't actually do anything
unless certain criteria are met.
The "bootcmd_fel" implementation proposed here first tests if an actual
FEL boot takes place (using the "fel_booted" env var), and secondly
checks that "fel_scriptaddr" was set (originating from the 'loader',
i.e. the sunxi-tools fel utility). If both checks pass, then it will
try to execute the boot script (boot.scr) at the given address. In case
of an error (e.g. an invalid image), the source command might return
"false", causing "distro_bootcmd" to proceed with the next boot target.

for the boot.scr address, then the corresponding environment
variable fel_scriptaddr gets set.
misc_init_r() also sets (or clears) the "fel_booted" variable depending
on the active boot device, using the same logic as spl_boot_device().
The goal is to provide sufficient information (within the U-Boot
environment) to make intelligent decisions on how to continue the boot
process, allowing specific customizations for the "FEL boot" case.

sunxi: (mksunxiboot) signature to indicate "sunxi" SPL variant
This patch follows up on a discussion of ways to improve support
for the sunxi FEL ("USB boot") mechanism, especially with regard
to boot scripts, see:
https://groups.google.com/d/msg/linux-sunxi/wBEGUoLNRro/rHGq6nSYCQAJ
The idea is to convert the (currently unused) "pad" bytes in the
SPL header into an area where data can be passed to U-Boot. To
do this safely, we have to make sure that we're actually using
our "sunxi" flavor of the SPL, and not the Allwinner boot0.
The modified mksunxiboot introduces a special signature to the
SPL header in place of the "pub_head_size" field. This can be
used to reliably distinguish between compatible versions of sunxi
SPL and anything else (older variants or Allwinner's boot0).

sunxi: move SPL-related definitions to platform-specific include
The sunxi platform currently doesn't seem to make any use of the
asm/arch-sunxi/spl.h file. This patch moves some declarations from
tools/mksunxiboot.c into it.
This enables us to reuse those definitions when extending the
sunxi board code (boards/sunxi/boards.c).

x86: chromebook_link: Expand early malloc() memory
Now that PCI bridges are probed before relocation we need additional memory.
Each PCI bridge takes 240 bytes at present since it uses the same uclass as
the PCI controller. Probably we should split this out so that bridges have
their own uclass.
Expand the memory on link so that it works correctly.

For some workloads - dfu test @ Odroid XU3 (sending 8MiB file) -
and SD cards (e.g. MicroSD Kingston 4GiB, Adata 4GiB)
the default timeout is to short.
The new value - 4 minutes (240 seconds) - is the same as the one used in
Linux kernel driver. Such fix should be good enough until we come up
with better fix for this issue.

tools: gen_eth_addr: add getpid() to time(0) to avoid duplicated seed
As 'time(0) | getpid()' will have a lot of duplicated value. It is not a
expected behavior. We expect different value for the seed when when run
it in many times.
So this patch will left shift the getpid() and add to time(0). That
avoid duplicated value.
Test command is like:
% RUN=0; while [ $RUN -lt 10000 ]; do
tools/gen_eth_addr; RUN=$(($RUN+1)); done | sort | uniq | wc -l
10000

ARM: hikey: hi6220: Migrate over to DM_SERIAL and use UART3 by default.
Use DM for the pl01x serial driver on hikey. Also allow UART0 or
UART3 to be chosen via Kconfig.
By default we now output to UART3 as the latest version of ATF outputs
to this UART. Also UART3 comes out on the LS connector, as opposed to
UART0 which goes to a unpopulated header.
As part of this change we also enable CONFIG_BOARD_EARLY_INIT_F and
call the pinmux configuration code for the UART. Before we were
relying on ATF having already configured the pin configuration.
NB: Upstream Linux kernel doesn't yet support UART3, so serial console
will still be output on UART0 when booting a upstream kernel.
