This patchset contains several works on the sunxi DesignWare DRAM
controllers.
The 1st patch made an option for H3-like DRAM controllers
(DesignWare ones), which can ease further import of alike controllers.
The 2nd and 3rd patches are for supporting 16-bit DW DRAM controllers,
in order to add V3s DRAM support (The controller on V3s is 16-bit).
The 4th patch adds bank detection code, in order to support some DDR2
chips.
The 5th patch adds a framework for select DRAM type and timing -- it's
needed for boards that use DRAM chips rather than DDR3.
The 6th patch enables dual rank detection in the DW DRAM code on SoCs
except R40. For R40 the dual rank facility is still not so clear, so
it's
temporarily disabled.
The 7th~9th patches enables support for DRAM initialization and SPL
for
the V3s SoC, which integrates a DDR2 chip.
The 10th and 11th patches adds support for LPDDR3, with the stock
boot0
timing. (Seen in A83T boot0 source and some leaked H5/R40 libdram
source)
The 12th patches adds a defconfig for SoPine w/ official baseboard,
which
utilizes LPDDR3.
All those changes looks good to me. I'll wait for Jens' review
however, since he knows that part much more than I do.
It seems that Jens haven't appeared for several months...
I grep'ed my local IRC log, and his latest appearance is in March.
After then he's still in the people list, however he haven't said
anything since March.
The IRC client of him seems to be running on a VPS, so it's always
online.
Jens, can you see this?
Thanks!
Maxime
