The SD UHS SDR12, SDR25, SDR50, SDR104, DDR50 and MMC HS200, HS400
modes all use 1.8V signaling, while all the legacy modes use 3.3V
signaling. While there are extra modes which use 1.2V signaling,
the existing hardware does not support those.

pinmux and the rest implies UHS mode pinmux. This prevents the
massive case statement from growing further. Moreover, it fixes
an edge case where during SD 1.8V switch, the bus mode is still
set to default while the signaling is already set to 1.8V, which

Andre Przywara [Thu, 25 Oct 2018 09:23:07 +0000 (17:23 +0800)]
sunxi: store DRAM size in SPL header

At the moment we rely on the infamous get_ram_size() function to learn
the actual DRAM size in U-Boot proper. This function has two issues:
1) It only works if the DRAM size is a power of two. We start to see
boards which have 3GB of (usable) DRAM, so this does not fit anymore.
2) As U-Boot has no notion of reserved memory so far, it will happily
ride through the DRAM, possibly stepping on secure-only memory. This
could be a region of DRAM reserved for OP-TEE or some other secure
payload, for instance. It will most likely crash in that case.

As the SPL DRAM init routine has very accurate knowledge of the actual
DRAM size, lets propagate this wisdom to U-Boot proper.
We re-purpose a currently reserved word in our SPL header for that.
The SPL itself stores the detected DRAM size there, and bumps the SPL
header version number in that case. U-Boot proper checks for a valid
SPL header and a high enough version number, then uses the DRAM size
from there. If the SPL header field is not sufficient, we fall back to
the old DRAM scanning routine.

Part of the DRAM might be present and probed by SPL, but not accessible
by the CPU. They're restricted in the main U-Boot binary, when accessing
the DRAM size from SPL header.
