There are two versions of imx6ul pico SOMs: one with 256MB and another
one with 512MB of RAM.Convert to SPL so that both versions can be supported. This patch
doesn't rework the clock initialization to avoid changing the behavior
in this same patch, so it will be cleaned up in future.Currently only the 256MB is tested/supported.

AM654 allows for booting from primary or backup boot media.
Both media can be chosen individually based on switch settings.
ROM looks for a valid image in primary boot media, if not found
then looks in backup boot media. In order to pass this boot media
information to boot loader, ROM stores a value at a particular
address. Add support for reading this information and determining
the boot media correctly.Signed-off-by: Lokesh Vutla

On K3 family SoCs, once the ROM loads image on R5, M3 resets R5 and
expects to start executing from 0x0. In order to handle this ROM
updates the boot vector of R5 such that first 64 bytes of image load
address are mapped to 0x0.In this case, it is SPL's responsibility to jump to the proper image
location. So, update the PC with address of reset vector(like how
other exception vectors are handled), instead of branching to reset.Reviewed-by: Tom Rini

Four different boards had different options for enabling cache

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 .
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.Signed-off-by: Masahiro Yamada

You do not need to use the typedefs provided by compiler.

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.The following size changed apply to omap3_logic using GCC.

In commit a1274cc94a20 ("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.[1] https://sourceware.org/bugzilla/show_bug.cgi?id=23571

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:

This patch improves cpu hotplug, previous cpu_off
implementation is NOT safe, a CPU can NOT power down
itself in runtime, it will cause system bus hang due
to pending transaction. So need to use other online
CPU to kill it when it is ready for killed.Here use SRC parameter register and a magic number
of ~0 as handshake for killing a offline CPU,
when the online CPU checks the psci_affinity_info,
it will help kill the offline CPU according to
the magic number stored in SRC parameter register.Signed-off-by: Anson Huang

The existing imx_watchdog driver is compatible with mx25 chipsets.
Add a WDOG1_BASE_ADDR define for the base address and enable the driver
in watchdog's Makefile.To use the driver, a board must define CONFIG_IMX_WATCHDOG and
CONFIG_HW_WATCHDOG.This fixes an issue when booting an mx25 chip via usb/serial. In this
case, the boot rom will always enable the watchdog. If u-boot is running
in interactive mode and the watchdog is not serviced, the system is
rebooted when the watchdog expires.Signed-off-by: Martin Kaiser

On iMX7D SabreSD board, the QSPI has pins conflict with EPDC (default).
To use QSPI, users have to rework the board (de-populate R388-R391, R396-R399
populate R392-R395, R299, R300). So we add new DTS file and new defconfig
dedicated for QSPI.Other changes to support the DM QSPI:
- Add QSPI node and alias spi0.
- Modify spi4 (spi-gpio) node and add alias spi5 for it to avoid req
conflict
- Add EPDC node in imx7d.dtsi and disable it in imx7d-sdb-qspi.dts to
align with kernel and also present the conflict.
- Add -u-boot.dtsi to modify compatible string of mx25l51245g@0 to
"spi-flash"
- Remove iomux settings of qspi in board codes which is not needed
for DM driver.Signed-off-by: Ye Li
