ARM: am33xx: Always inhibit init/refresh during DDR phy init
A couple of commits have modified the am33xx/am437x ddr2/ddr3
initialization path to fix certain issues, but have had the side effect
of causing L3 noc errors during initialization. The two commits are:
The EMIF_REG_INITREF_DIS_MASK bit still needs to be set for all
platforms. This delays initialization and refresh until a later stage.
The 500us timer can be programmed for platforms that require it
and for platforms that don't require it. It is currently hardcoded
for 400MHz systems. For systems with a higher memory frequency
this needs to be a larger value, and for systems with a lower
memory frequency this can be a lower value. This can be
considered a separate issue and corrected in a later commit.

In certain circumstances it comes in handy to be able to boot into a second
U-Boot. But as of now it is not possible to boot a U-Boot binary that is inside
a FIT image, which is problematic for projects that e.g. need to guarantee a
unbroken chain of trust from SOC all the way into the OS, since the FIT signing
mechanism cannot be used.
This patch adds the capability to load such FIT images.
An example .its snippet (utilizing signature verification) might look
like the following:
commit 1f807a9f32aa ("ARM: keystone2: Refactor MSMC macros to avoid
left under a macro KS2_MSMC_SEGMENT_QM_PDSP which is no longer valid.
This, in effect disabled DMA coherency for QM PDSP.
Given that msmc_k2hkle_common_setup is valid for all K2H/K/L/E SoCs,
the #ifdef should been removed in the first place. Do the same.
A feasible way to communicate certain errors for devices that have no
other way of signalling besides LEDs is to flash these LEDs. For errors
in U-Boot, a script that utilizes the led and sleep commands would be a
practicable way, but currently the sleep command can only delay for an
integral amount of seconds, which is too slow to create an easily
noticeable pattern for flashing LEDs.
Therefore, this patch adds support for fractions (down to .001 seconds)
to the sleep command.
The parsing is kept minimal, simplistic and as robust as possible: After
converting the passed string using simple_strtoul and multiplying it
with 1000, we search for the first dot, convert the three characters
after that into a number (if they are not numbers, we ignore the
fractional part and just use the delay we got from simple_strtoul), and
add this number to the delay.

When signing images, we repeatedly call fit_add_file_data() with
successively increasing size values to include the keys in the DTB.
Unfortunately, if large keys are used (such as 4096 bit RSA keys), this
process fails sometimes, and mkimage needs to be called repeatedly to
integrate the keys into the DTB.
This is because fit_add_file_data actually returns the wrong error
code, and the loop terminates prematurely, instead of trying again with
a larger size value.
This patch corrects the return value by fixing the return value of
fdt_add_bignum, fixes a case where an error is masked by a unconditional
setting of a return value variable, and also removes a error message,
which is misleading, since we actually allow the function to fail. A

spl: Lightweight UBI and UBI fastmap support
Booting a payload out of NAND FLASH from the SPL is a crux today, as
it requires hard partioned FLASH. Not a brilliant idea with the
reliability of todays NAND FLASH chips.
The upstream UBI + UBI fastmap implementation which is about to
brought to u-boot is too heavy weight for SPLs as it provides way more
functionality than needed for a SPL and does not even fit into the
restricted SPL areas which are loaded from the SoC boot ROM.
So this provides a fast and lightweight implementation of UBI scanning
and UBI fastmap attach. The scan and logical to physical block mapping
code is developed from scratch, while the fastmap implementation is
lifted from the linux kernel source and stripped down to fit the SPL
needs.
The text foot print on the board which I used for development is:
6854 0 0 6854 1abd
drivers/mtd/ubispl/built-in.o
Attaching a NAND chip with 4096 physical eraseblocks (4 blocks are
reserved for the SPL) takes:
In full scan mode: 1172ms
In fastmap mode: 95ms
The code requires quite some storage. The largest and unknown part of
it is the number of fastmap blocks to read. Therefor the data
structure is not put into the BSS. The code requires a pointer to free
memory handed in which is initialized by the UBI attach code itself.
See doc/README.ubispl for further information on how to use it.
This shares the ubi-media.h and crc32 implementation of drivers/mtd/ubi
There is no way to share the fastmap code, as UBISPL only utilizes the
slightly modified functions ubi_attach_fastmap() and ubi_scan_fastmap()
from the original kernel ubi fastmap implementation.

ARM: tegra: pick up actual memory size
On Tegra186, U-Boot is booted by the binary firmware as if it were a
Linux kernel. Consequently, a DTB is passed to U-Boot. Cache the address
of that DTB, and parse the /memory/reg property to determine the actual
RAM regions that U-Boot and subsequent EL2/EL1 SW may actually use.
Given the binary FW passes a DTB to U-Boot, I anticipate the suggestion
that U-Boot use that DTB as its control DTB. I don't believe that would
work well, so I do not plan to put any effort into this. By default the
FW-supplied DTB is the L4T kernel's DTB, which uses non-upstreamed DT
bindings. U-Boot aims to use only upstreamed DT bindings, or as close as
it can get. Replacing this DTB with a DTB using upstream bindings is
physically quite easy; simply replace the content of one of the GPT
partitions on the eMMC. However, the binary FW at least partially relies
on the existence/content of some nodes in the DTB, and that requires the
DTB to be written according to downstream bindings. Equally, if U-Boot
continues to use appended DTBs built from its own source tree, as it does

use. When U-Boot is chain-loaded by another bootloader, CPU registers may
contain useful information such as system configuration information. This
feature mirrors the equivalent ARMv7 feature.

Rev A03 of P2180 requires some PMIC programming adjustments, yet the
PMIC's own OTP has not been updated. Consequently, U-Boot must make
these changes itself.
NVIDIA's syseng team has confirmed that these changes can be enabled on
all board revisions without issue.

ARM: tegra: add IVC protocol implementation
IVC (Inter-VM Communication) protocol is a Tegra-specific IPC (Inter
Processor Communication) framework. Within the context of U-Boot, it is
typically used for communication between the main CPU and various
auxiliary processors. In particular, it will be used to communicate with
the BPMP (Boot and Power Management Processor) on Tegra186 in order to
manipulate clocks and reset signals.

ARM: tegra: unify Tegra186 Makefile a bit
Many files in arch/arm/mach-tegra are compiled conditionally based on
Kconfig variables, or applicable to all platforms. We can let the main
Tegra Makefile handle compiling (or not) those files to avoid each SoC-
specific Makefile needing to duplicate entries for those files. This
leaves the SoC-specific Makefiles to compile truly SoC-specific code.
In the future, we'll hopefully add Kconfig variables for all the other
files, and refactor those files, and so reduce the need for SoC-specific
Makefiles and/or ifdefs in the Makefiles.

ARM: tegra: split p2771-0000 build
There are multiple versions of p2771-0000 board. There are SW visible
incompatible differences between the versions, and they are relevant to
U-Boot. Create separate "A02" and "B00" defconfigs (named after the first
and/or only board rev the defconfig supports) so that users can select
which build they want.
With the minimal set of HW currently enabled in U-Boot, the differences
are irrelevant, hence the DT files aren't different. However, that will
change in a future patch.

The enum conversion broke the compatibility with existing uImage
files. Reverting 555f45d8f916 will cause build error unfortunately,
so here is a more easy fix.
I dug the git history and figured out the gap was introduced by
commit 1117cbf2adac ("nios: remove nios-32 arch"). So, I revived
IH_ARCH_NIOS just for filling the gap.
I added comments to each enum block. Once we assign a value to
IH_... it is not allowed to change it.
