6e7df1d151 global: Finish CONFIG -> CFG migration
At this point, the remaining places where we have a symbol that is
defined as CONFIG_... are in fairly odd locations. While as much dead
code has been removed as possible, some of these locations are simply
less obvious at first. In other cases, this code is used, but was
defined in such a way as to have been missed by earlier checks.  Perform
a rename of all such remaining symbols to be CFG_... rather than
CONFIG_...

As this is used on both ARM and PowerPC platforms, this needs to be

448e2b6327 event: Correct dependencies on the EVENT framework
The event framework is just that, a framework. Enabling it by itself
does nothing, so we shouldn't ask the user about it. Reword (and correct
typos) around this the option and help text. This also applies to
DM_EVENT and EVENT_DYNAMIC. Only EVENT_DEBUG and CMD_EVENT should be
visible to the user to select, when EVENT is selected.

With this, it's time to address the larger problems. When functionality
uses events, typically via EVENT_SPY, the appropriate framework then
must be select'd and NOT imply'd. As the functionality will cease to
work (and so, platforms will fail to boot) this is non-optional and
where select is appropriate. Audit the current users of EVENT_SPY to
have a more fine-grained approach to select'ing the framework where
used. Also ensure the current users of event_register and also select
EVENT_DYNAMIC.

1b697407ae powerpc/mpc85xx: socrates: Re-enable building u-boot-socrates.bin
U-Boot build system builds final U-Boot binary for socrates board in custom
file u-boot-socrates.bin (instead of standard u-boot.bin). Output target
file u-boot-socrates.bin is generated by binman as defined in board binman
config file arch/powerpc/dts/socrates-u-boot.dtsi.

But binman was disabled in commit 5af42eafd7 ("Makefile: Reduce usage of
custom mpc85xx u-boot.bin target") for all mpc85xx boards which do not use
standard powerpc binman config file arch/powerpc/dts/u-boot.dtsi and boards
which do not require binman at all.

The only such mpc85xx board is socrates. So since that commit, U-Boot does
not final binary for socrates board anymore.

Fix this issue by re-enabling binman for socrates board. And build process
starts again producing u-boot-socrates.bin binary.

Note that build process for this socrates board always produce u-boot.bin
binary which is broken and not usable for socrates board. Long term
solution should be to disable building broken binary u-boot.bin and then
renaming u-boot-socrates.bin to u-boot.bin, or switching to use common
powerpc binman config file arch/powerpc/dts/socrates-u-boot.dtsi (if it is
possible).

88c2e9157c PowerPC: Update dependencies on *SYS_MPC85XX_NO_RESETVEC
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.

138b6061a1 powerpc/mpc85xx: Improve disabling of SPE instructions
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.

c0d0569cf6 powerpc/mpc85xx: Pass correct cpu compiler flags
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.

mmc: fsl_esdhc_spl: Add support for builds without CONFIG_SYS_MMC_U_BOOT_OFFS
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
required to specify fixed offset to U-Boot proper at SPL compile time.

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

powerpc: mpc85xx: Fix loading U-Boot proper from SD card in SPL
Change 8-byte alignment of SPL binary to just 4-byte alignment as objcopy
trims trailing zero bytes when converting ELF file to RAW binary.

This is same fix for SPL linker script as was done fix for U-Boot linker
script in commit e8c0e0064c ("powerpc: mpc85xx: Fix CONFIG_OF_SEPARATE
support").

It is required for the patch "mmc: fsl_esdhc_spl: Add support for builds
without CONFIG_SYS_MMC_U_BOOT_OFFS" which triggered this issue in SPL.

powerpc: mpc85xx: Fix check for CONFIG_SDCARD
Commit d433c74eec ("Convert CONFIG_SDCARD et al to Kconfig") converted
SYS_EXTRA_OPTIONS=SDCARD or SPIFLASH to config options CONFIG_SDCARD and
CONFIG_SPIFLASH, but left one occurance unchanged.

Fix this.

44366be10a board: freescale: p1_p2_rdb_pc: Turn off watchdog before reset
P1/P2 RDB boards have external max6370 watchdog connected to CPLD and this
watchdog is not deactivated on board reset. So if it is active during board
reset, it can trigger another reset when CPU is booting U-Boot. To prevent
possible infinite reset loop caused by external watchdog, turn it off
before reset.

Do it via a new board_reset_prepare() callback which is called from
do_reset() function before any reset sequence.

7e962cb132 board: freescale: p1_p2_rdb_pc: Avoid usage of CPLD's system reset register
CPLD's system reset register is buggy and requires workaround in U-Boot.
So use this kind of board reset only when there is no other reset option.

Introduce a new board_reset_last() callback which is last-stage
board-specific reset and implement CPLD's system reset in this new
board_reset_last() callback instead of board_reset() callback.
