c68721d93a arm: K3: am654: Unlock control module registers during init
By default the device control module registers are locked,
preventing any writes to its registers.
Unlock those registers as part of the init flow.

e00646099f arm: K3: am654: Add support for boot device detection
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.

f70b72e353 arm: K3: Update _start instruction
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.

The patch applied in 2010
"cmd_fpga: cleanup help and check parameters"
(sha1: a790b5b2326be9d7c9ad9e3d9b51a8bfabc62d07"
was adding this checking

+       if (dev == FPGA_INVALID_DEVICE) {
+               puts("FPGA device not specified\n");
+               op = FPGA_NONE;
+       }

which simply broke one command flow which was
setenv fpga <dev>
fpga loadmk <addr> // legacy image
fpga loadmk <addr>:<fit_image_name> //fit image

Also this sequence for FIT image is completely broken
setenv fpga <dev>
setenv fpgadata <addr>:<fit_image_name>
fpga loadmk
(Note: For legacy images this is working fine).

even from code I don't think this has ever worked properly
for fit image (dev = FPGA_INVALID_DEVICE should be rejected
by fpga core). Fit image support was in 2008 added by:
"[new uImage] Add new uImage fromat support to fpga command"
(sha1: c28c4d193d)

Just a summary of these facts that none found this for pretty long time
it shouldn't be a problem to remove this flow (without fpga dev)
completely to simplify the code.

8961c8ad25 tools: mkimage: Ensure munmap unmaps the same length that was mapped
The set_header call in kwbimage.c adds a checksum to the end of the
image in addition to setting up the header. It 'helpfully' updates the
st_size to match the fact that the file is now longer. However, mkimage
uses this length in the munmap call. This can lead to unmapping an extra
page, of perhaps required data. When this happens, a SEGV can occur.

To prevent this from happening, the munmap call now uses the same length
that was passed to mmap. This could also have been fixed by not changing
the length in kwbimage.c, however changing it in the main file means
that other plugins will also not fall for the same trap.

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. "
