c5437e5b8a imx: Enable ACTLR.SMP bit for all i.MX cortex-a7 platforms
According to the Cortex-A7 TRM, for ACTLR.SMP bit "You must ensure this bit
is set to 1 before the caches and MMU are enabled, or any cache and TLB
maintenance operations are performed".
ROM sets this bit in normal boot flow, but when in serial download mode,
it is not set.
Here we add it in u-boot as a common flow for all i.MX cortex-a7 platforms,
including mx7d, mx6ul/ull and mx7ulp.

a673025535 serial: zynq: Initialize uart only before relocation
This issue was found when OF_LIVE was enabled that there are scrambled

Chip ID:	zu3eg
Watchdog: Started��j�   sdhci@ff160000: 0, sdhci@ff170000: 1

I found a solution for this problem exactly the same as I found later in
serial_msm fixed by:
"serial: serial_msm: initialize uart only before relocation"
(sha1: 7e5ad796bc)

What it is happening is that output TX fifo still contains chars to be
sent and _uart_zynq_serial_init() resets TX fifo even in the middle of
transfer.

c7df098a71 arm64: zynqmp: accept an absolute path for PMUFW_INIT_FILE
The value of PMUFW_INIT_FILE is prefixed with "$(srctree)/", thus
forcing it to be a relative path inside the U-Boot source tree. Since
the PMUFW is a binary file generated outside of U-Boot, the PMUFW
binary must be copied inside the U-Boot source tree before the
build.

This generates a few problems:

 * if the source tree is shared among different out-of-tree builds,
   they will pollute (and potentially corrupt) each other
 * the source tree cannot be read-only
 * any buildsystem must add a command to copy the PMUFW binary
 * putting an externally-generated binary in the source tree is ugly
   as hell

Avoid these problems by accepting an absolute path for
PMUFW_INIT_FILE. This would be as simple as removing the "$(srctree)/"
prefix, but in order to keep backward compatibility we rather use the
shell and readlink to get the absolute path even when starting from a
relative path.

Since 'readlink -f' produces an empty string if the file does not
exist, we also add a check to ensure the file configured in
PMUFW_INIT_FILE exists. Otherwise the build would exit successfully,
but produce a boot.bin without PMUFW as if PMUFW_INIT_FILE were empty.

Tested in the 12 possible combinations of:
 - PMUFW_INIT_FILE empty, relative, absolute, non-existing
 - building in-tree, in subdir, in other directory

58bc69d20a efi_loader: Allocate memory handle for mem dp
When we boot using memdp (bootefi on an address without previous
load that populates the device path) then the memory device path
we pass in is not backed by any handle.

That can result in weird effects. For example grub gets very grumpy
about this inside the efi_net module and just loops endlessly.

So let's expose a simple handle that the memory device path is backed
on. That way any code that looks for the device the dp is on, finds
one.

When building with -pedantic the current definition of EFI_GUID() causes
an error 'initializer element is not constant'.

Currently EFI_GUID() is used both as an anonymous constant and as an
intializer. A conversion to efi_guid_t is not allowable when using
EFI_GUID() as an initializer. But it is needed when using it as an
anonymous constant.

We should not use EFI_GUID() for anything but an initializer. So let's
introduce a variable where needed and remove the conversion.
