3f20321ad8 board: arm: Add support for Broadcom BCM7260
Add support for loading U-Boot on the Broadcom 7260 SoC.  This port
assumes Broadcom's BOLT bootloader is acting as the second stage
bootloader, and U-Boot is acting as the third stage bootloader, loaded
as an ELF program by BOLT.

93b283d49f ARM: CPU: arm926ejs: Consolidate cache routines to common file
Four different boards had different options for enabling cache
that were virtually all the same.  This consolidates these
common functions into arch/arm/cpu/arm926ejs/cache.c

This also has the positive side-effect of enabling cache on
the Davinci (da850) boards.

c76382ff7f mmc: fsl_esdhc: enable HS400 feature
The strobe dll code is ported from Linux Kernel:
drivers/mmc/host/sdhci-esdhc-imx.c
The comments are from the above file,
"For HS400 eMMC, there is a data_strobe line. This signal is generated
by the device and used for data output and CRC status response output
in HS400 mode. The frequency of this signal follows the frequency of
CLK generated by host. The host receives the data which is aligned to the
edge of data_strobe line. Due to the time delay between CLK line and
data_strobe line, if the delay time is larger than one clock cycle,
then CLK and data_strobe line will be misaligned, read error shows up.
So when the CLK is higher than 100MHz, each clock cycle is short enough,
host should configure the delay target. "

dee37fc99d Remove <inttypes.h> includes and PRI* usages in printf() entirely
In int-ll64.h, we always use the following typedefs:

  typedef unsigned int         u32;
  typedef unsigned long        uintptr_t;
  typedef unsigned long long   u64;

This does not need to match to the compiler's <inttypes.h>.
Do not include it.

The use of PRI* makes the code super-ugly.  You can simply use
"l" for printing uintptr_t, "ll" for u64, and no modifier for u32.

de39dc7162 arm: armv7-a: Compile and tune for armv7-a instead of armv5
arch/arm/Makefile references armv5 for backwards compatibility with
older compilers.  This patch removes those references to armv5,
since by now newer compilers are required which should have armv7
support enabled.

The Makefile also also has a list of options for mtune, but the
entry for CONFIG_CPU_V7A is empty, so this patch tunes the
CPU_V7A architecture to generic-armv7-a.

f850371997 fdt: fix get_next_memory_node()
The get_next_memory_node() always sets mem to -1 , which is incorrect,
because then every iteration of memory bank parsing will start from the
first memory bank instead of the previous one.

On systems with 1 memory bank defined in DT and CONFIG_NR_DRAM_BANKS=4 ,
like ie. r8a77965-salvator-x , this will result in U-Boot incorrectly
reporting four identical memory banks with the same memory configuration.

Fix this by setting mem to startoffset value, which restores the behavior
before the fixed patch was applied.

792b204798 ARM: Specify aligned address for secure section instead of using attributes
In commit a1274cc94a ("ARM: Page align secure section only when it is
executed in situ"), we used output section attributes (the "ALIGN"
keyword after the colon) to specify the alignment requirements. Using
the constant "COMMONPAGE" there was recently broken in binutils 2.31 [1].

Binutils maintainer Alan Modra suggested the former method would still
work. Since both methods achieve the same result, this patch does just
that. This fixes the "reboot after bootm" issue we've been seeing on
sunxi when booting non-secure.

If the NAND chip is missing get_nand_dev_by_index() returns NULL. Fail
gracefully in this case.

57b620255e imx: mx7: add system suspend/resume support
This patch adds system suspend/resume support,
when linux kernel enters deep sleep mode, SoC will go
into below mode:

 - CA7 platform goes into STOP mode;
 - SoC goes into DSM mode;
 - DDR goes into self-refresh mode;
 - CPU0/SCU will be powered down.

When wake up event arrives:

 - SoC DSM mdoe exits;
 - CA7 platform exit STOP mode, SCU/CPU0 power up;
 - Invalidate L1 cache;
 - DDR exit self-refresh mode;
 - Do secure monitor mode related initialization;
 - Jump to linux kernel resume entry.

Belwo is the log of 1 iteration of system suspend/resume:

The resume entry function has to initialize stack pointer before calling
C code, otherwise there will be an external abort occur, in additional,
invalidate L1 cache must be done in secure section as well, so this
patch also adds assembly code back and keep it as simple as possible.

b059837850 imx: mx7: add gpc initialization for low power mode
Add i.MX7D GPC initialization for low power mode
support like system suspend/resume from linux kernel:

 - Pending IOMUXC IRQ to workaround GPC state machine issue;
 - Mask all GPC interrupts for M4/C0/C1;
 - Configure SCU timing;
 - Configure time slot ack;
 - Configure C0/C1 power up/down timing;
 - Configure wakeup source mechanism;
 - Disable DSM/RBC related settings.
