2fd81be11c common: board_r: move init_addr_map() to init.h
asm/mmu.h include is currently guarded by CONFIG_ADDR_MAP ifdef because
the header is only present on arm and powerpc. In order to remove the
dependency on this header and the associated ifdef, move init_addr_map()
declaration to init.h, since it is only called during the common init
sequence.

7ee2016d61 ide: Drop unused CONFIG options
CONFIG_SYS_ATA_PORT_ADDR is not used in the code anymore. Drop it and use
ATA_PORT_ADDR() locally instead.

Drop CONFIG_IDE_RESET_ROUTINE and CONFIG_IDE_SWAP_IO which are also
unused.

53f06134ed Convert CONFIG_NAND_FSL_ELBC et al to Kconfig
This converts the following to Kconfig:
   CONFIG_NAND_FSL_ELBC
   CONFIG_NAND_FSL_IFC

Note that a number of PowerPC platforms had previously enabled
CONFIG_NAND_FSL_ELBC without CONFIG_MTD_RAW_NAND, and now they no longer
enable the option, reducing the size of a few functions.

ab92b38a01 Finish converting CONFIG_SYS_CACHELINE_SIZE to Kconfig
We move the SYS_CACHE_SHIFT_N options from arch/arm/Kconfig to
arch/Kconfig, and introduce SYS_CACHE_SHIFT_4 to provide a size of 16.
Introduce select statements for other architectures based on current
usage.  For MIPS, we take the existing arch-specific symbol and migrate
to the generic symbol.  This lets us remove a little bit of otherwise
unused code.

- 0 otherwise.

The purpose was to fix up device tree properties "peripheral-frequency"

However the implementation on both u-boot and linux was only
for a Freescale SDK release. The linux part implementation had never
been upstreamed. These code should not have been exist on u-boot
mainline.

Let's remove the powerpc part changes but keep the changes in
fsl_esdhc driver. The changes in fsl_esdhc driver could be utilized
to support SD UHS and eMMC HS200/HS400 speed modes for current
Layerscape ARM platforms.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

Convert the powerpc architecture to make use of the new asm-generic/io.h
to provide address mapping functions. As powerpc can actually perform
non-identity mapping between physical & virtual addresses we can't
simply make use of the generic phys_to_virt() & virt_to_phys()
functions. However since map_physmem() already effectively implemented
the same thing as virt_to_phys() we can simply implement virt_to_phys()
instead of map_physmem() & use the generic map_physmem(). We also drop
the no-op unmap_physmem().

This has only been build-tested, feedback from architecture maintainers
is welcome.

As those 3 functions can't me defined at the same time, let's
rename them print_reginfo() to avoid the #ifdefs
The name is kept generic as it is not at all dependent on
powerpc arch and any other arch could want to also print
such information.

In addition, as the Makefile compiles cmd/reginfo.c only when
CONFIG_CMD_REGINFO is set, there is no need to enclose the U_BOOT_CMD
definition inside a #ifdef CONFIG_CMD_REGINFO

Lets all remove the #ifdefs around the U_BOOT_CMD as this

907208c452 powerpc: Partialy restore core of mpc8xx
CS Systemes d'Information (CSSI) manufactures 8xx boards for
critical communication systems. Those boards have been
running U-Boot since 2010 and will have to be maintained
until at least 2027.

commit 5b8e76c35e
("powerpc, 8xx: remove support for 8xx") orphaned those boards
by removing support for the mpc8xx CPU.

This commit partially restores support for the 8xx, with the
following limitations:
- Restores support for MPC866 and MPC885 only
- Does not restore IDE, PCMCIA, I2C, USB
- Does not restore examples
- Does not restore POST
- Does not restore Ethernet on SCC
- Does not restore console on SCC
- Does not restore bedbug and kgdb support

As the 866 and 885 do not support the following features,
they are not restored either:
- VIDEO / LCD
- RTC clock

The CPM uCODE patch is not restored either, because:
- 866 and 885 already have support for I2C and SPI relocation
without a uCODE patch
- relocation of SMC, I2C or SPI is only needed for using SCCs
for Ethernet or QMC

The dynamic setup/calculation of clocks is removed, we
expect the target being use with the clock and PLPRCR register
defined in the configuration.
All the clock settings for 8xx prior to 866 is removed as
well as we now only support 866 and 885.

This code is mature and addresses mature boards. Therefore
all code enclosed in '#if 0/#endif' and '#if XX_DEBUG/#endif'
is unneeded.

The following files are not restored by this patch:

- arch/powerpc/cpu/mpc8xx/bedbug_860.c
- arch/powerpc/cpu/mpc8xx/fec.h
- arch/powerpc/cpu/mpc8xx/kgdb.S
- arch/powerpc/cpu/mpc8xx/plprcr_write.S

- post/cpu/mpc8xx/uart.c

- post/cpu/mpc8xx/watchdog.c

Some of the restored files are not located in a proper location.
In order to keep traceability of the changes, they will be
moved to their correct location and moved to Kconfig in a
followup patch.

This patch also declares CSSI as point of contact for the update
of the 8xx platform, as those boards are the only ones still
being maintained on the 8xx area. A later patch will add
those boards to the tree.

98f705c9ce powerpc: remove 4xx support
There was for long time no activity in the 4xx area.
We need to go further and convert to Kconfig, but it
turned out, nobody is interested anymore in 4xx,
so remove it.
