If the core runs at higher than x3 speed of the platform, there is
possiblity about sev instruction to getting missed by other cores.
This is because of SoC Run Control block may not able to sample
the EVENTI(Sev) signals.
Configure Run Control and EPU to periodically send out EVENTI signals to
wake up A57 cores.

When one core is released, other cores may not have valid entry
address. Those cores are trapped by "wfe" and wait for further
instruction. When their address is set, they need to be kicked
off by "sev".

This patch addresses a problem mentioned recently on this mailing list:
[1].
In that posting a LS1021 based system was locking up at about 5 minutes
after boot,but the problem was mysteriously related to the toolchain
used for building u-boot.Debugging the problem reveals a stuck
interrupt 29 on the GIC.
It appears Freescale's LS1021 support in u-boot erroneously sets the
64-bit ARM generic PL1 physical time CompareValue register to all-ones
with a 32-bit value.This causes the timer compare to fire 344 seconds
after u-boot configures it.Depending on how fast u-boot gets the
kernel booted,this amounts to about 5-minutes of Linux uptime before
locking up.
Apparently the bug is masked by some toolchains. Perhaps this is
explained by default compiler options, word sizes, or binutils versions.
To fix the above issue, the generic physical timer is disabled
before jumping to the OS.

serial_init() reads global_data, since global_data is not yet
initialized, this can cause unwanted behaviour leading to QSPI XIP boot
hang. Also, since serial_init() is anyways called later from
boar_init_f(), it does not make sense to do the same in s_init().
Tested on AM437x IDK EVM with QSPI XIP boot.

The 3.4 kernel from the Allwinner SDK is clocking AHB1 at 200MHz
on Allwinner H3 and using PLL6 as the clock source (PLL6/3).
This can be verified by reading the value of the AHB1_APB1_CFG_REG
register via /dev/mem. It always reads as 0x3180 regardless of
the current cpufreq operating point. So this configuration should
be safe for use in U-Boot too.
PLL6 also needs to be configured before it is used as the clock
source, according to the "CCU / Programming Guidelines" section
of the Allwinner manual.
The current low AHB1 clock speed is limiting the USB transfer
speed when booting via FEL. This patch can increase the FEL USB
transfer speed from ~510 KB/s to ~950 KB/s.

Make spl_*_load_image() functions return a value instead of
hanging if a problem is encountered. This enables main spl code
to make the decision whether to hang or not, thus preparing
it to support alternative boot devices.
Some boot devices (namely nand and spi) do not hang on error.
Instead, they return normally and SPL proceeds to boot the
contents of the load address. This is considered a bug and
is rectified by hanging on error for these devices as well.

BeagleBoard X15 (http://beagleboard.org/x15) support in u-boot does
actually support two different platform configuration offered by
TI. In addition to BeagleBoard X15, it also supports the TMDXEVM5728
(or more commonly known as AM5728-evm).
Information about the TI AM57xx EVM can be found here
http://www.ti.com/tool/tmdxevm5728
The EVM configuration is 1-1 compatible with BeagleBoard X15 with the
additional support for mPCIe, mSATA, LCD, touchscreen, Camera, push
button and TI's wlink8 offering.
Hence, we rename the beagle_x15 directory to am57xx to support TI
EVMs that use the AM57xx processor. By doing this we have common code
reuse. This sets the stage to have a common u-boot image solution for
multiple TI EVMs such as that already done for am335x and am437x. This
sets the stage for upcoming multiple TI EVMs that share the same code
base.
NOTE: Commit eae7ae185335 ("am437x: Add am57xx_evm_defconfig using
CONFIG_DM") introduced DT support for beagle_x15 under am57xx_evm
platform name. However, this ignored the potential confusion arising for
users as a result. To prevent this, existing beagle_x15_defconfig is
renamed as am57xx_evm_nodt_defconfig to denote that this is the "non
device tree" configuration for the same platform. We still retain
am57xx-beagle-x15.dts at this point, since we just require the common
minimum dts.
As a result of this change, users should expect changes in build
procedures('make am57xx_evm_nodt_defconfig' instead of 'make
beagle_x15_defconfig'). Hopefully, this would be a one-time change.

The code such as PSCI in section named secure is bundled with
u-boot image, and when bootm, the code will be copied to their
runtime address same to compliation/linking address -
CONFIG_ARMV7_SECURE_BASE.
When compile the PSCI code and link it into the u-boot image,
there will be relocation entries in .rel.dyn section for PSCI.
Actually, we do not needs these relocation entries.
If still keep the relocation entries in .rel.dyn section,
r0 at line 103 and 106 in arch/arm/lib/relocate.S may be an invalid
address which may not support read/write for one SoC.
102 /* relative fix: increase location by offset */
103 add r0, r0, r4
104 ldr r1, [r0]
105 add r1, r1, r4
106 str r1, [r0]
So discard them to avoid touching the relocation entry in
arch/arm/lib/relocate.S.

In order for noncached_init() to operate correctly, SoCs must set up a
custom page table with fine-grained (2MiB) sections, which can be
configured from noncached_init().
This is currently performed by arch/arm/cpu/armv8/{fsl-lsch3,zynqmp}/cpu.c
by cut/pasting and re-implementing mmu_setup, enable_caches(), etc. There
are some other reasons for the duplication there though, such as enabling
icache early, and enabling dcaching earlier with a different configuration.
This change makes mmu_setup() a weak implementation, so that the MMU setup
code can be replaced without having to duplicate other code that calls it.
