Most architectures currently supported by U-Boot use trivial
implementations of map_to_physmem & virt_to_phys which simply cast a
physical address to a pointer for use a virtual address & vice-versa.
This results in a lot of duplicate implementations of these mapping
functions.
The set of functions provided by different architectures also differs,
with some having implementations of phys_to_virt & others not. A later
patch will make use of phys_to_virt in architecture-neutral code, and so
requires that it be provided for all architectures.
This patch introduces an asm-generic/io.h which provides generic
implementations of address mapping functions, allowing the duplication
of them between architectures to be removed. Once architectures are
converted to make use of this generic header it will also ensure that
all of phys_to_virt, virt_to_phys, map_physmem & unmap_physmem are
provided. The 2 families of functions differ in that map_physmem may
create dynamic mappings whilst phys_to_virt may not & therefore is more
limited in scope but doesn't require information such as a length &
flags.
This patch doesn't convert any architectures to make use of this generic
header - later patches in the series will do so.

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

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.

Some boards cannot access pre-relocation data after relocation. Reserve
space for this and copy it during preparation for relocation.
Signed-off-by: Simon Glass <sjg@chromium.org>
At present bootstage uses the data section of the image to store its
information. There are a few problems with this:
- It does not work on all boards (e.g. those which run from flash before
relocation)
- Allocated strings still point back to the pre-relocation data after
relocation
Now that U-Boot has a pre-relocation malloc() we can use this instead,
with a pointer to the data in global_data. Update bootstage to do this and
set up an init routine to allocate the memory.
Now that we have a real init function, we can drop the fake 'reset' record
and add a normal one instead.
Note that part of the problem with allocated strings remains. They are
reallocated but this will only work where pre-relocation memory is
accessible after relocation.

At present malloc_base/_limit/_ptr are not initialised in spl_init() when

spl_relocate_stack_gd().
However if CONFIG_SPL_STACK_R_MALLOC_SIMPLE_LEN is not defined, we now
skip setting up the memory area in spl_init() which is obviously wrong.

Certain GPIO devices have the capability to switch their GPIOs into
open-drain mode, that is, instead of actively driving the output
(Push-pull output), the pin is connected to the collector (for a NPN
transistor) or the drain (for a MOSFET) of a transistor, respectively.
The pin then either forms an open circuit or a connection to ground,
depending on the state of the transistor.
This patch adds functions to the GPIO uclass to switch GPIOs to
open-drain mode on devices that support it.
