Generate 'u-boot-splx4.sfp' which consist of 4 SPL images required
for booting up Cyclone5/Arria10.
By default, this 'u-boot-splx4.sfp' is generated without extra
padding after each SPL image.
For Cyclone5, 'u-boot-splx4.sfp' contains:
4 x SPL(64KB) = 256KB
For Arria10, 'u-boot-splx4.sfp' contains:
4 x SPL(256KB) = 1024KB
For Cyclone5 using NAND flash image layout for 128 KB memory blocks,
user can 'make' the following target to generate 4 SPL images with
padding:
make u-boot-spl-padx4.sfp
'u-boot-spl-padx4.sfp' contains four 128KB SPL images (each 64KB SPL is
followed by 64KB of zero-padding).
4 x (SPL(64KB) + zero-padding(64KB)) = 512KB

Now that PIE works when U-Boot is started from ROM, let's enable
CONFIG_POSITION_INDEPENDENT, which allows to load U-Boot also via

Currently we hard-code the number and initial addresses of QEMU's flash
banks, even though our code is perfectly able to gather the same
information from the DTB provided by QEMU.
This is especially annoying, since we have two slightly different
U-Boot configurations ("bare-metal" vs. loaded via Arm Trusted
Firmware), which need to be selected at build time.
Drop the two hard coded alternatives, and use
CONFIG_SYS_MAX_FLASH_BANKS_DETECT instead, which relies on the DTB to
figure out the actual flash configuration at runtime.
Signed-off-by: Andre Przywara <andre.przywara@arm.com>
Currently selecting CONFIG_POSITION_INDEPENDENT also forces us to use an
initial stack pointer relative to the beginning of the BSS section.
This makes some sense, because this should be writable memory anyway.
However the BSS section is not cleared or used until later in the
setup process (after relocation), so memory nearby might not be
available early enough to host the initial stack. This is an issue if
U-Boot is loaded from (Flash-)ROM, for instance.
Allow CONFIG_INIT_SP_RELATIVE to be turned off by a board's config, to
be able to select a fixed stack pointer, for instance in known good
DRAM.
This will help QEMU utilising PIE, when it's loaded to (Flash-)ROM.

When we build an arm64 target and enable POSITION_INDEPENDENT, we were
skipping our build-time dynamic relocation fixup routine (STATIC_RELA).
This was probably done because we didn't need it in this case, as the
PIE fixup routine in start.S would take care of that at runtime.
However when we now skip this routine (upon detecting that the fixup
offset is 0), this might lead to uninitialised pointers.
Remove the exception, so that we always do the build-time relocation.
NOTE: GNU binutils starting with v2.27.1 do this build-time relocation
automatically, to be in-line with other architecures. So on newer
toolchains our manual fixup is actually not needed. It doesn't hurt to
have it, though, so that we keep compatibility with the popular Linaro
toolchains, which lack this feature.
