Hi everyone,
This is v3 of the A31 support series. This series add basic (UART and MMC)
support for Allwinner's A31 SoC. The patches, excluding the first one,
were cherry-picked from u-boot-sunxi. Due to the difference between u-boot
mainline and u-boot-sunxi, some patches were rearranged or squashed to
better fit the current state of u-boot, and not introduce any build breaks.
It follows Ian's initial merge method of sun7i support: introducing various
components first, then enabling them in the last commit. I tried to keep
the commits separate, thus retaining the original author and Signed-off-bys.
Patch 1 updates the current UART pinmuxing code to use macros for pull-up
values. This is for existing platforms, but is included as it would conflict
with patch 7.
Patch 2 adds a wrapper around "func(USB, usb, 0)" in BOOT_TARGET_DEVICES
to deal with breakage when USB support is not enabled.
Patch 3 adds memory addresses for some hardware blocks new in sun6i.
Patch 4 adds support for the new PRCM (power reset and clock management)
block, which also contains PLL bias voltage control.
Patch 5 adds support for the clock module. This patch is a bunch of
different sun6i related patches on the clock code, from when sun6i
support was introduced to u-boot-sunxi, up to its current form.
This is done to avoid various conflicts and needlessly introducing
then removing macros.
Patch 6 adds mmc support on sun6i.
Patch 7 adds uart0 pin macros.
Patch 8 adds uart0 muxing on sun6i.
Patch 9 enables sun6i support.
Patch 10 adds a defconfig for the Colombus board, which is an A31
evaluation board.
Changes since v2:
- Added Maxime Ripard as maintainer of Colombus board
Changes since v1:
- Added macros for sun6i uart pinmuxes (patch 7)
- Use gpio macros when muxing uarts (patch 1, 8)
- Clarify what is enabled in PRCM (patch 4)
- Dropped old comments in commit message from Hans (patch 4)
- Use setbits helpers in PRCM code (patch 4)
- Drop SPL code block from clock code (patch 5)
- Make mmc code use fifo in register structure definition, and
add reserved area to adjust for sun6i's different fifo address
(patch 6)
- Rewrite patch 9 commit message to reflect what is supported
- Split out Colombus board defconfig into separate patch (patch 10)
Cheers
