2017-01-15imx233: workaround hardware dma bugAmaury Pouly1-0/+34
This bug mostly affects the ZEN and ZEN X-Fi and hangs the lcdif dma randomly on boot. Change-Id: I4255db90d87737b7a70d1d53e3ef84e4e14c8c13
2016-05-28imx233: generate register headers using headergen_v2 and update code for itAmaury Pouly1-27/+30
NOTE: this commit does not introduce any change, ideally even the binary should be almost the same. I checked the disassembly by hand and there are only a few differences here and there, mostly the compiler decides to compile very close expressions slightly differently. I tried to run the new code on several targets to make sure and saw no difference. The major syntax changes of the new headers are as follows: - BF_{WR,SET,CLR} are now superpowerful and allows to set several fileds at once: BF_WR(reg, field1(value1), field2(value2), ...) - BF_CS (use like BF_WR) does a write to reg_CLR and then reg_SET instead of RMW - there is no more need for macros like BF_{WR_,SET,CLR}_V, since one can simply BF_WR with field_V(name) - the old BF_SETV macro has no trivial equivalent and is replaced with its its equivalent for BF_WR(reg_SET, ...) I also rename the register headers: "regs/regs-x.h" -> "regs/x.h" to avoid the redundant "regs". Final note: the registers were generated using the following command: ./headergen_v2 -g imx -o ../../firmware/target/arm/imx233/regs/ desc/regs-stmp3{600,700,780}.xml Change-Id: I7485e8b4315a0929a8edb63e7fa1edcaa54b1edc

2013-06-17imx233: fix dma for stmp3600 and stmp3700, improve supportAmaury Pouly1-9/+58
Add finer granularity to start command: now commands can be prepared, schedule and semaphore increased independently. Change-Id: Ib1ed1f20f4b46dc61b6dbab6ddec8b54e3d832b9

2012-08-18imx233: small dma changes, update debug screenAmaury Pouly1-4/+12
Reduce DMA maximum transfer size since transfering 64Kb requires to set a size of 0 and it's not worth adding checks everywhere to handle this special case. Also add statistics about unaligned transfer (wrt to cache). Update debug screen accordingly and simplify it so it can fit smaller screens too. Change-Id: I18391702f5e100a21f6f8d1ebab28d9f2bd8c66f

2011-09-05imx233:fuze+: major memory and usb reworkAmaury Pouly1-9/+18
- now identity map dram uncached and have a cached and buffered virtual alias - rework dma to handle virtual to physical pointers conversion - fix lcd frame pointer - implement usb detection properly - implement bootloader usb properly - allow the bootloader to disable MMC windowing (useful for recovery) git-svn-id: svn:// a1c6a512-1295-4272-9138-f99709370657
2011-07-23imx233/fuze+: huge reworkAmaury Pouly1-1/+47
- enable MMU -rework lcd frame buffer - add rtc/adc/power stubs (or not) - fix a few MMC related defines (hopefully) - implement cache handling for DMA - more SD work - add keymap (based on clip) - add virtual buttons - update linker scripts - big step toward apps actually compiling git-svn-id: svn:// a1c6a512-1295-4272-9138-f99709370657
