sunxi: cleanup sunxi-common.h

2024-01-29T01:18:51+00:00

The sunxi-common.h configs header used to contain a lot of random
Allwinner platform related constants, but over the years we moved a lot
of those definitions out there.

Clean up the file to remove outdated comments which are leftovers from
the olden days. Also remove the definition of LOW_LEVEL_SRAM_STACK,
which is actually used nowhere in the whole source tree.

This also uses the opportunity to add some section comments that helps
structuring the header file and improving readability.

sunxi: refactor serial base addresses to avoid asm/arch/cpu.h

2023-10-22T22:41:52+00:00

At the moment we have each SoC's memory map defined in its own cpu.h,
which is included in include/configs/sunxi_common.h. This will be a
problem with the introduction of Allwinner RISC-V support.

Remove the inclusion of that header file from the common config header,
instead move the required serial base addresses (for the SPL) into a
separate header file. Then include the original cpu.h file only where
we really need it, which is only under arch/arm now.

This disentangles the architecture specific header files from the
generic code.

sunxi: h616: lower SPL stack address to avoid BROM data

2023-01-21T01:32:23+00:00

When using the USB OTG FEL mode on the Allwinner H616, the BootROM
stores some data at the end of SRAM C. This is also the location where
we place the initial SPL stack, so it will overwrite this data.
We still need the BROM code after running the SPL, so should leave that
area alone.
Interestingly this does not seem to have an adverse effect, I guess on
the "way out" (when we return to FEL after the SPL has run), this data
is not needed by the BROM, for just the trailing end of the USB operation.
However this is still wrong, and we should not clobber BROM data.

Lower the SPL stack address to be situated right below the swap buffers
we use in sunxi-fel: that should be out of the way of everyone else.

kbuild: Remove uncmd_spl logic

2022-12-23T15:15:13+00:00

At this point in the conversion there should be no need to have logic to
disable some symbol during the SPL build as all symbols should have an
SPL counterpart.

The main real changes done here are that we now must make proper use of
CONFIG_IS_ENABLED(DM_SERIAL) rather than many of the odd tricks we
developed prior to CONFIG_IS_ENABLED() being available.

sunxi: remove unused CONFIG_MMC_SUNXI_SLOT

2022-12-14T22:31:06+00:00

There is a CONFIG_MMC_SUNXI_SLOT definition in our sunxi_common.h config
header, which was used to note the first MMC controller to initialise.
The definition in that header was always set to 0, with no easy way of
overriding this, and certainly none of the existing boards made any use
of that (non-)feature.
Remove that definition and replace it with a constant 0 in the only
user, in board.c. It turns out that this is safe, as this is only used
in the SPL, and the BROM also unconditionally initialises MMC0.
This also removes the last legacy config symbol with SUN*I in it from
the whitelist.

global: Move remaining CONFIG_SYS_* to CFG_SYS_*

2022-12-05T21:06:08+00:00

The rest of the unmigrated CONFIG symbols in the CONFIG_SYS namespace do
not easily transition to Kconfig. In many cases they likely should come
from the device tree instead. Move these out of CONFIG namespace and in
to CFG namespace.
