| * imx: mx6: fix USB bmode to use reserved valueStefan Agner2016-10-04-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently the bmode "usb" uses BOOT_CFG1 to 0x01, -which means BOOT_CFG1[7:4] is set to b0000. According to Table 8-7 Boot Device Selection this is NOR/OneNAND and not Reserved. Use 0x10 which leads to b0001, which is a Reserved boot device. With that the SoC reliably falls back to the serial loader.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | i.MX6ULL has two 128 bits fuse banks, bank 7 and bank 8, while other banks use 256 bits. So we have to adjust the word and bank index when accessing the bank 8. When in command line `fuse read 8 0 1`, you can image `fuse read 7 4 1` in the ocotp driver implementation for 6ULL. When programming, we use word index, so need to fix bank7/8 programming for i.mx6ull. For example: fuse prog 8 3 1; The word index is (8 << 3 | 3) --> 67. But actully it should be (7 << 3 | 7) ---> 63. So fix it. Signed-off-by: Peng Fan <peng.fan@nxp.com> Cc: Stefano Babic <sbabic@denx.de>

| * mx6sabresd: Make SPL DDR configuration to match the DCD tableFabio Estevam2016-10-04-154/+197
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using SPL on i.mx6 we frequently notice some DDR initialization mismatches between the SPL code and the non-SPL code. This causes stability issues like the ones reported at 7dbda25ecd6d7c ("mx6ul_14x14_evk: Pass refsel and refr fields to avoid hang") and also: http://lists.denx.de/pipermail/u-boot/2016-September/266355.html . As the non-SPL code have been tested for long time and proves to be reliable, let's configure the DDR in the exact same way as the non-SPL case. The idea is simple: just use the DCD table and write directly to the DDR registers. Retrieved the DCD tables from: board/freescale/mx6sabresd/mx6q_4x_mt41j128.cfg and board/freescale/mx6sabresd/mx6qp.cfg (NXP U-Boot branch imx_v2015.04_4.1.15_1.0.0_ga) This method makes it easier for people converting from non-SPL to SPL code. Other benefit is that the SPL binary size is reduced from 44 kB to 39.9 kB. Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com>

For example OS may set "reboot_image" environment variable to "recovery" inorder to boot recovery image by SPL.

* | kbuild: generate u-boot.cfg as a byproduct of include/autoconf.mkMasahiro Yamada2016-10-07-46/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our build system still parses ad-hoc CONFIG options in header files and generates include/autoconf.mk so that Makefiles can reference them. This gimmick was introduced in the pre-Kconfig days and will be kept until Kconfig migration is completed. The include/autoconf.mk is generated like follows: [1] Preprocess include/common.h with -DDO_DEPS_ONLY and retrieve macros into include/autoconf.mk.tmp [2] Reformat include/autoconf.mk.dep into include/autoconf.mk with tools/scripts/define2mk.sed script [3] Remove include/autoconf.mk.tmp Here, include/autoconf.mk.tmp is similar to u-boot.cfg, which is also generated by preprocessing include/config.h with -DDO_DEPS_ONLY. In other words, there is much overlap among include/autoconf.mk and u-boot.cfg build rules. So, the idea is to split the build rule of include/autoconf.mk into two stages. The first preprocesses headers into u-boot.cfg. The second parses the u-boot.cfg into include/autoconf.mk. The build rules of u-boot.cfg in Makefile and spl/Makefile will be gone.

* | kbuild: move no_new_adhoc_configs_check to "all" target commandMasahiro Yamada2016-10-07-8/+6
| | | | | | | | | | | | | | | | | | | | | | I am going to move the build rule of u-boot.cfg. Before that, no_new_adhoc_configs_check must be tweaked to not depend on it. The ad-hoc option check can be done at the end of build, along with other checks. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Glass <sjg@chromium.org>
