Linux stopped the use of keyword 'boolean' in Kconfig.

cpsw tries to flush dcache which is not in the range of PKTALIGN.
Because of this the following warning comes while flushing:

This commit allows injecting a board/platform/device-specific post-
processing function into the FIT image data loading process, which can
include modifying the size and altering the starting source address of
an image data artifact. This might be desired to do things like strip
headers or footers attached to the images before they were packaged into
the FIT, or to perform operations such as decryption or authentication.
Introduce new configuration option CONFIG_FIT_IMAGE_POST_PROCESS to
allow controlling this feature. If enabled, a platform-specific post-
process function must be provided.

As the sLD3 Boot ROM has a complex page table, it is difficult to

Commit 4b50369f

 ("ARM: uniphier: create early page table at
run-time") broke the ROM boot mode for PH1-sLD3 SoC, because the
run-time page table creation requires the outer cache register
access but the page table in the sLD3 Boot ROM does not straight-map
virtual/physical addresses.

The idea here is to check the current page table to determine if
it is a straight map table.  If not, adjust the outer cache register
base.

start.S prepares a stackframe that is later rendered unusable by appending

Instead the reserved space has to be put first. Then the stackframe can

When a target device is 0 bytes long, there's no point in exposing it to
the user. Let's just skip them.

Also, when an offset is passed into the efi disk creation, we should
remove this offset from the total number of sectors we can handle.
