[PATCH v5 0/4] Select CONFIG_64BIT for sandbox64 and x86_64
Picking up a series from Dan Carpenter and applying requested changes for v2.
I had previously set CONFIG_64BIT for arm64. This patchset does the same thing for sandbox and x86_64. (Mips and riscv were already doing it). This CONFIG option is used in the Makefile to determine if it's a 32 or 64 bit system for the CHECKER.
Makefile 1052 # the checker needs the correct machine size 1053 CHECKFLAGS += $(if $(CONFIG_64BIT),-m64,-m32)
Changes in v5: - Previous version mistakenly simplified the change to bloblist.c, so reinstate the full change in order to fix those platforms that broke.
Changes in v4: - Add help text to describe new symbol CONFIG_SPL_64BIT - Split the statement in bloblist.c to be more readable
Changes in v3: Added a new patch 1/4 to make fixes to the source needed by the sandbox patch 2/4. Updated 3/4 to account for x86 being built with a 64 bit U-Boot proper but a 32 bit SPL. Added another patch 4/4 to fix an incorrect use of CONFIG_PHYS_64BIT which should be CONFIG_64BIT at the request of Tom Rini.
Changes in v2: Resubmitted by Andrew Goodbody with changes requested by reviewer
Andrew Goodbody (4): sandbox: Correct guard around readq/writeq sandbox: select CONFIG_64BIT for sandbox x86: select CONFIG_64BIT for X86_64 test: lib: Use CONFIG_64BIT to detect 64 bit compile

In include/linux/io.h the declarations of ioread64 and iowrite64 which make use of readq/writeq are guarded with CONFIG_64BIT so guard the sandbox declarations of readq and writeq also with CONFIG_64BIT.

Select CONFIG_64BIT so that we pass the -m64 option (instead of -m32) to static analysis tools.

Select CONFIG_64BIT so that we pass the -m64 option (instead of -m32) to static analysis tools. Introduce CONFIG_SPL_64BIT and select it for architectures other than x86 with 64 bit builds. Do not select it for x86 builds as x86 uses a 32 bit SPL. Ensure that when limits are set they use CONFIG_64BIT for U-Boot proper and CONFIG_SPL_64BIT for SPL. This is to allow for the 32 bit SPL build used by x86.

Changes in v5: - The change to bloblist.c in the previous version was mistakenly simplified and no longer contained the needed fix which was to use a variable that could hold a 64bit value when compiled as 64bit. This version reinstates the full fix from V3 when it was a separate patch.
Changes in v4: - Add help text to describe new symbol CONFIG_SPL_64BIT - Split statement in bloblist.c to make it more readable
Changes in v3: Introduce CONFIG_SPL_64BIT to allow for x86 building a 32 bit SPL and a 64 bit U-Boot proper.
Changes in v2: Corrected commit title to be x86 not sandbox

Should use CONFIG_64BIT to detect a 64 bit compile and not CONFIG_PHYS_64BIT. This allows more platforms to run the full test code.

Applied to u-boot/next, thanks!
