A kernel hang is observed when running wandboard 3.14 kernel and
going to the lowest operational point of cpufreq:# ifconfig eth0 down
# echo 1 > /sys/class/graphics/fb0/blankThe problem is caused by incorrect setting of the REFR field
of register MDREF. Setting it to 4 refresh commands per refresh
cycle fixes the hang.Signed-off-by: Fabio Estevam

Authentication of images in Falcon Mode is not supported. Do not enable
SPL_OS_BOOT when TI_SECURE_DEVICE is enabled. This prevents attempting
to directly load kernel images which will fail, for security reasons,
on HS devices, the board is locked if a non-authenticatable image load
is attempted, so we disable attempting Falcon Mode.Signed-off-by: Andrew F. Davis

The option SPL_SPI_SUPPORT is used to enable support in SPL for loading
images from SPI flash, it should not be used to determine the build type
of the SPL image itself. The ability to read images from SPI flash does
not imply the SPL will be booted from SPI flash.Unconditionally build SPI flash compatible SPL images.

Depending on the boot media, different images are needed
for secure devices. The build generates u-boot*_HS_* files
as appropriate for the different boot modes.For AM33xx devices additional image types are needed for
various SPL boot modes as the ROM checks for the name of
the boot mode in the file it loads.Signed-off-by: Andrew F. Davis

The config option AM33XX is used in several boards and should be
defined as a stand-alone option for this SOC. We break this out
from target boards that use this SoC and common headers then enable
AM33XX on in all the boards that used these targets to eliminate any
functional change with this patch.This is similar to what has already been done in
9de852642cae ("arm: Kconfig: Add support for AM43xx SoC specific Kconfig")
and is done for the same reasons.Signed-off-by: Andrew F. Davis

Adds a secure dram reservation fixup for secure
devices, when a region in the emif has been set aside
for secure world use. The size is defined by the
CONFIG_TI_SECURE_EMIF_TOTAL_REGION_SIZE config option.Signed-off-by: Daniel Allred

If the ending portion of the DRAM is reserved for secure
world use, then u-boot cannot use this memory for its relocation
purposes. To prevent issues, we mark this memory as PRAM and this
prevents it from being used by u-boot at all.Signed-off-by: Daniel Allred

After EMIF DRAM is configured, but before it is used,
calls are made on secure devices to reserve any configured
memory region needed by the secure world and then to lock the
EMIF firewall configuration. If any other firewall
configuration needs to be applied, it must happen before the
lock call.Signed-off-by: Daniel Allred

Create a few public APIs which rely on secure world ROM/HAL
APIs for their implementation. These are intended to be used

Adds start address and size config options for setting aside
a portion of the EMIF memory space for usage by security software
(like a secure OS/TEE). There are two sizes, a total size and a
protected size. The region is divided into protected (secure) and
unprotected (public) regions, that are contiguous and start at the
start address given. If the start address is zero, the intention
is that the region will be automatically placed at the end of the
available external DRAM space.Signed-off-by: Daniel Allred

rockchip platform have a protocol to pass the the kernel reboot mode to bootloader
by some special registers when system reboot. In bootloader we should read it and take action.We can only setup boot_mode in board_late_init becasue "setenv" need env setuped.
So add CONFIG_BOARD_LATE_INIT to common header and use a entry "rk_board_late_init"
to replace "board_late_init" in board file.Signed-off-by: Jacob Chen

Update PPLL to 676MHz and PMU_PCLK to 48MHz, because:
1. 48MHz can make sure the pwm can get exact 50% duty ratio, but 99MHz
can not,
2. We think 48MHz is fast enough for pmu pclk and it is lower power cost
than 99MHz,
3. PPLL 676 MHz and PMU_PCLK 48MHz are the clock rate we are using
internally for kernel,it suppose not to change the bus clock like pmu_pclk
in kernel, so we want to change it in uboot.Signed-off-by: Kever Yang

The all current Rockchip SoCs supporting 4GB of ram have problems
accessing the memory region 0xfe000000~0xff000000. Actually, some IP
controller can't address to, so let's limit the available range.This patch fixes a bug which found in miniarm-rk3288-4GB board. The
U-Boot was relocated to 0xfef72000, and .bss variants was also
relocated, such as do_fat_read_at_block. Once eMMC controller transfer
data to do_fat_read_at_block via DMA, DMAC can't access more than
0xfe000000. So that DMAC didn't work sane.Signed-off-by: Ziyuan Xu

As boot monitor contains a mkimage header, it can be loaded at any location.
So, have a common addr_mon address across all keystone2 SoCs. And also
making sure that boot monitor is installed early during default boot to
avoid any overlapping with other images.Signed-off-by: Lokesh Vutla
Reviewed-by: Tom Rini -
Given that boot monitor image is being generated to a specific target location
depending on the SoC and U-boot relies on addr_mon env variable to be aligned
with boot monitor target location. When ever the target address gets updated in
boot monitor, it is difficult to sync between u-boot and boot monitor and also
there is no way to update user that boot monitor image is updated.To avoid this problem, boot monitor image is being generated with mkimage
header. Adding support in mon_install command for parsing this header.Signed-off-by: Suman Anna
