An issue in the TI secure image generation tool causes the ROM to
load the SPL at a different load address than what is specified by
CONFIG_ISW_ENTRY_ADDR while doing a peripheral boot.
This causes the SPL to fail on secure devices during peripheral
boot.
The TI secure image generation tool has been fixed so that the SPL
will always be loaded at 0x403018E0 by the ROM code for both
peripheral and memory boot modes. am43x hs defconfig file have been
updated to reflect this change.
r2dplus: fixup CONFIG_SYS_TEXT_BASE to account arch/sh changes
This change allows to reserve enough space at the end of board SDRAM
to store two copies of U-Boot and malloc heap.
Due to selection of the CONFIG_SYS_TEXT_BASE the second code/data
copying is not avoided, first of all this may depend on a used
toolchain, secondly at this point some level of volatility is wanted
to do more platform changes and do not care about probably changed
calculated in runtime relocation offset.
sh: generate position independent code for all platforms
Finally add fpic compilation option to produce relocatable code.
Note that this requires to define CONFIG_NEEDS_MANUAL_RELOC for all
board files, also relocation support still has some limitations
(e.g. a developer should care not to overwrite the executing code or
memset() with zeroes not yet relocated data on malloc init etc.),
which may be fixed while switching to PIE.
Due to short investigation the architecture code is not ready for PIE
linking, this will require some manipulations with .dyn* sections.
sh: share the correct version of start.S among all cpus
It is easy to note that SH2/SH3/SH4 start.S code is practically
the same with a minor difference for SH2 where a short data header is
present. To avoid unwanted code duplication and to automatically
convert SH2 and SH3 platforms to generic board support move fixed SH4
start.S into arch/sh/lib/start.S and share it among all platforms.

sh4: fix start.S by calling board_init_f() after first code relocation
Like on ARM platform keep the first code relocation from a U-boot
image storage to RAM at CONFIG_SYS_TEXT_BASE, then pass execution to a
generic board_init_f() with empty GD flags. If CONFIG_SYS_TEXT_BASE is
equal to a calculated by board_init_f() relocation address there will
be no more code and data copy, however it's worth to mention that the
first copy happens even if $pc on _start is the same as
CONFIG_SYS_TEXT_BASE, on practice this works without a problem.
Also note that _sh_start is renamed back to _start to correct
gd->mon_len calculation by setup_mon_len(), the opposite rename was
done in pre-generic board commit 2024b968ee9 ("sh: Fix build in start.S").

imx: mx6: ddr: add register MPZQLP2CTL for LPDDR2
Add constants for the MPZQLP2CTL DDR register for both
banks to allow setting the LPDDR2 timing values in
.cfg files using a named constant instead of hex addresses
as is currently done in mx6slevk and other board files.

arm: imx: wandboard: fix compile error if CONFIG_VIDEO is deactivated
When I tried to deactivate VIDEO support for the Wandboard, it still
tried to initialize the Framebuffer and so on. That is the reason for
the added ifdefs. CONFIG_VIDEO is enabled in the configuration as default
and therefore nothing changes for the default user.
The structs mx6dl_i2c2_pad_info and mx6q_i2c2_pad_info are only available
when CONFIG_IPUV3 are set and should not be tried to access, when that
define is not defined.

tbs2910: Make Ethernet functional again
Configure the PHY to output a 125MHz clk from CLK_25M and set tx clock delay.
This patch is similar to commit 4b6035da482cccda06aeb419634f99937c9fc783
("mx6sabresd: Make Ethernet functional again").
The ipu has two display interfaces. Make the used one a parameter
in struct display_info_t instead of using unconditionally DI0.
DI0 is the default setting.

If CONFIG_SPL_LIBCOMMON_SUPPORT is not defined there is a lone case statement

ARM: mx6: add MMC2 boot device detection support in SPL
Check BOOT_CFG2[3:4] to determine which SD/MMC port is selected to boot
from. If MMC2 is selected return BOOT_DEVICE_MMC2. In all other cases
return BOOT_DEVICE_MMC1, as we do not have corresponding macro for MMC3
and MMC4.

armv7: psci: cpu_off: flush D-Cache before disable D-Cache
Before disable cache, need to first flush cache.
There maybe dirty data in D-Cache before disable D-Cache.
After disable D-Cache, the first store instructions in
psci_v7_flush_dcache_all will directly store registers
{r4-r5, r7, r9-r11, lr} to memory.
If there is dirty data before disable D-Cache,
psci_v7_flush_dcache_all will flush data to memory,
and may overwrite the memory that hold the registers
{r4-r5, r7, r9-r11, lr}.
So before disable cache, first flush D-Cache.

vexpress64: Juno: Change PCI buss addresses for IO to start from zero.
Juno uses a 1:1 mapping between CPU and PCI addresses for IO. First,
that will trip devices that cannot use more than 16 bits of addresses
for IO, second it is un-necessary as the system can handle zero-based
PCI addresses just fine.
Change the mapping to start IO bus addresses from zero.
