In 96699f097a ("powerpc: mpc85xx: Use binman to embed dtb inside
U-Boot") we introduce CONFIG_MPC85XX_HAVE_RESET_VECTOR and do so via
Kconfig. However, much later in de47ff5363 ("Convert
CONFIG_SYS_MPC85XX_NO_RESETVEC to Kconfig") I converted the symbol that
is the inverse of this to Kconfig. This should have included a
dependency on the first symbol as they are logically opposite.
The dependency being missing lead to some platforms being broken at
runtime due to discarding the require reset vector.

All vector instructions on powerpc mpc85xx must not be used because U-Boot
does not enable them. Usage cause random crashes. SPE vector instructions
are already disabled by compiler flags, so disable also AltiVec and VSX
vector instructions.
Linux kernel disables AltiVec and VSX instructions too.

Specifying -mspe=no also disables usage of SPE instructions. It is
documented in "[PATCH,rs6000] make -mno-spe work as expected" email:
http://gcc.gnu.org/ml/gcc-patches/2008-04/msg00311.html
So replace -mspe=yes by -mspe=no, so make it clear that u-boot has to be
compiled without SPE instructions.
Linux kernel contains following Makefile code to achieve it:
# No SPE instruction when building kernel
# (We use all available options to help semi-broken compilers)
KBUILD_CFLAGS += $(call cc-option,-mno-spe)
KBUILD_CFLAGS += $(call cc-option,-mspe=no)
Do same for U-Boot.

When gcc's default cpu (selected by --with-cpu= during gcc's configure
phase) does not match target U-Boot board cpu then U-Boot binary does not
have to be compiled correctly. Lot of distributions sets gcc's default cpu
to generic powerpc variant which works fine.
U-Boot already pass -Wa,-me500 flag to gcc which instructs GNU AS to accept
e500 specific instructions when processing assembler source files (.S).
This affects also assembly files generated by gcc from C source files. And
because gcc for generic powerpc cpu puts '.machine ppc' at the beginning of
the generated assembly file, it basically overwrites -me500 flag by which
was GNU AS invoked (from U-boot build system).
It started to be an issue since binutils 2.38 which does not keep enabled
extra functional units selected by previous cpu. Hence issuing directive
'.machine ppc' (generated by gcc for generic powerpc) after '.machine e500'
(specifying at command line) disables usage of e500 specific instructions.
And compiling arch/powerpc/cpu/mpc85xx/tlb.c code throws following
assembler errors:
{standard input}: Assembler messages:
{standard input}:127: Error: unrecognized opcode: `tlbre'
{standard input}:418: Error: unrecognized opcode: `tlbre'
{standard input}:821: Error: unrecognized opcode: `msync'
{standard input}:821: Error: unrecognized opcode: `tlbwe'
{standard input}:884: Error: unrecognized opcode: `tlbsx'
This issue was already hit by Debian people and is reported in bug tracker:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1003490
Calling gcc with -mcpu=8540 flag fixes this issue because -mcpu=8540 tells
gcc to compile code for e500 core/cpu (overwriting gcc's default cpu) and
does not put '.machine ppc' directive into assembly anymore.
Also if gcc is invoked with -mcpu=8540 then it pass -me500 flag to GNU AS.
So it is unnecessary to manually specify -Wa,-me500 flag because it is
implicitly added.
Fix this issue properly by specifying correct -mcpu compiler flag for all
supported powerpc cores in U-Boot mpc85xx platform, which are: e500v1,
e500v2, e500mc, e5500 and e6500. For specifying e500v1 and e500v2 cores,
gcc has unintuitive -mcpu=8540 and -mcpu=8548 flag names, for other cores
-mcpu matches core name.
The only difference between gcc's -mcpu=8540 and -mcpu=8548 flags is
support for double precision floating point SPE instructions. As U-Boot
does not use floating point, it is fine to use -mcpu=8540 for both e500v1
and e500v2 cores. Moreover gcc 9 completely removed e500 floating point
support, so since gcc 9 -mcpu=8548 is just alias to -mcpu=8540.
Note that U-Boot's CONFIG_E500 option is set also for other cpus, not only
for e500v1 and e500v2. So do not check for CONFIG_E500 and rather set e500
as last fallback value when no other mpc85xx cpu matches.

When fixed offset via CONFIG_SYS_MMC_U_BOOT_OFFS is not specified then
expects that U-Boot proper is placed immediately after SPL without any
additional padding.
This allows to generate smaller SPL+U-Boot final binary as it is not

In this case offset to U-Boot proper is calculated at SPL compile time in

Building of final u-boot.bin binary for mpc85xx via binman is needed only
when inserting DTB binary in the middle of the u-boot ELF binary (before
.bootpg and .resetvec ELF sections).
These requirements are met when CONFIG_MPC85XX_HAVE_RESET_VECTOR is enabled
(= generating .bootpg/.resetvec sections) and CONFIG_OF_SEPARATE is enabled
(= inserting DTB binary).
So in all other cases use standard build procedure instead of custom

Currently Makefile produces final mpc85xx image when SPL is not used in
custom file u-boot-with-dtb.bin. It is quite confusing name as build
process produce also intermediate file standard file u-boot-dtb.bin (which
is just intermediate and not bootable). Other platforms use u-boot.bin
(UBOOT_BIN) as standard name for final bootable raw image.
So change Makefile rules and binman to produce final bootable file for
mpc85xx also into file u-boot.bin. There is just need for mpc85xx to not
define default rule for u-boot.bin then instruct binman (via DTS file) to
store final image into u-boot.bin (instead of u-boot-with-dtb.bin) and
finally rename target u-boot-with-dtb.bin to u-boot.bin.
With this change are also removed custom Makefile hacks for mpc85xx that it
produced non-standard output file. And also updated documentation.

QorIQ U-Boot binary for SD card booting compiled during build process
(either u-boot.bin or u-boot-with-spl.bin) cannot be directly loaded by
QorIQ pre-PBL BootROM. Compiled U-Boot binary first needs to be processed
by Freescale boot_format tool as described in doc/README.mpc85xx-sd-spi-boot
BootROM requires that image on SD card must contain special boot sector.
Implement support for generating this special boot sector directly in
U-Boot start code. Boot sector needs to be at the beginning of the image,
so when compiling only proper U-Boot without SPL then it needs to be in
proper U-Boot. When compiling SPL with proper U-Boot then it needs to be
only in SPL.
Support can be enabled by a new config option FSL_PREPBL_ESDHC_BOOT_SECTOR.
Via other two additional options FSL_PREPBL_ESDHC_BOOT_SECTOR_START and
FSL_PREPBL_ESDHC_BOOT_SECTOR_DATA it is possible to tune how final U-Boot
image could be stored on the SD card.
