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.

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.

Add the board DTS files for 14x14 EVK and 9x9 EVK. They are necessary

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

In Linux, the memory returned by kmalloc() is DMA-capable.
However, it is not true in U-Boot.
At a glance, kmalloc() in U-Boot returns address aligned with
ARCH_DMA_MINALIGN. However, it never pads the allocated memory.
This half-way house is completely useless because calling kmalloc()
and malloc() in this order causes a cache sharing problem.
Change the implementation to call malloc_cache_aligned(), which
allocates really DMA-capable memory.

As of today, the proposal of adding "acpi_rsdp_addr" to the kernel
boot protocol does not make its way to the kernel mainline. This
creates some confusion if we leave it in the U-Boot code base.

Note this eventually does a partial revert to commit 3469bf4274

At present Linux kernel loaded from U-Boot as an EFI payload does
not boot. This fills in kernel's boot params structure with the
required critical EFI information like system table address and
memory map stuff so that kernel can obtain essential data like
runtime services and ACPI table to boot.
With this patch, now U-Boot as an EFI payload becomes much more
practical: it is another option of kernel bootloader, ie, can be
a replacement for grub.

Copy missing Kernel patch to make SLEWCTRL_SLOW available in device tree
and to correct the value of SLEWCTRL_FAST.
After this patch, the Kernel and U-boot device tree settings for
SLEWCTRL have the same effect.
Original Kernel patch message:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=424e0f039bfa8a51fb5c5178b6ece8baa4996469
"
According to AM335x TRM, Document spruh73l, Revised February 2015,
Section 9.2.2 Pad Control Registers, setting bit 6 of the pad control
registers actually sets the SLEWCTRL value to slow rather than fast as
the current macro indicates. Introduce a new macro, SLEWCTRL_SLOW, that
sets the bit, and modify SLEWCTRL_FAST to 0 but keep it for
completeness. Current users of the macro (i2c and mdio) are left
unmodified as SLEWCTRL_FAST was the macro used and actual desired state.
Tested on am335x-gp-evm with no difference in software performance seen.
