This serials patches add mipi dsi support for rk3399. Except the basic mipi driver, we need also enable pmic rk808 for lcd power and enable i2c for rk808 communication. what's more, the needed clk and pwm for backlight is init in spl stage, make sure spl work first.

[U-Boot] [PATCH v5 0/3] Allwinner V3s and Lichee Pi Zero support (w/o SPL)
by Icenowy Zheng 08 Apr '17

08 Apr '17

Allwinner V3s is a SoC with single-core Cortex-A7 and 64MiB DRAM co-packaged in a eLQFP package, which is suitable for manual soldering. This patchset adds basic support for it. SPL support is still missing, due to some reworks on DRAM initialization code is needed.(the co-packaged DRAM is DDR2, but the DRAM initialization code currently only support DDR3.)

[U-Boot] [PATCH] ARCv2: SLC: Make sure busy bit is set properly on SLC flushing
by Alexey Brodkin 07 Apr '17

07 Apr '17

As reported in STAR 9001165532, an SLC control reg read (for checking busy state) right after SLC invalidate command may incorrectly return NOT busy causing software to NOT spin-wait while operation is underway. (and for some reason this only happens if L1 cache is also disabled - as required by IOC programming model) Suggested workaround is to do an additional Control Reg read, which ensures the 2nd read gets the right status.

[U-Boot] Low priority request for info about alternative to #ifdef
by James Chargin 07 Apr '17

07 Apr '17

Hi I've seen periodic discussion on the U-Boot mailing list of alternatives to #ifdef. I need a bit more information about one specific alternative, but in my searches of the source for 2017.03, I can't find examples that might help me. Also, my memory of this is a dim so I'm not sure I'm looking for the right thing. Is there something that is similar to "#ifdef CONFIG_*" but looks more like "if_defined(CONFIG_*)" and relies on compile/link time elimination of unused code? Thanks for your time.

[U-Boot] [PATCH v3] spl: net: Add FIT image support over network boot
by Andrew F. Davis 07 Apr '17

07 Apr '17

FIT support in the net boot case is much like the RAM boot case in that we load our image to "load_addr" and pass a dummy read function into "spl_load_simple_fit()". As the load address is no longer hard-coded to the final execution address, RAW image loading will rely on "load_addr" pointing to the execution address as they should have before.
