2019-07-11arm: mach-omap2: am33xx: Init pinmux before clockMarek Vasut
The board_early_init_f() inits clock before initing pinmux. However, the clock configuration code might need to adjust PMIC settings of a PMIC on I2C bus (e.g. board/ti/am335x/board.c does that). If the I2C bus pin muxing is not configured before attempting to communicate with the PMIC, the communication will silently fail and the prcm_init() may configure fast enough CPU clock that the default voltage provided by the PMIC would be insufficient and the platform would become unstable.

2019-07-11cmd: Add 'bcb' command to read/modify/write BCB fieldsEugeniu Rosca
'Bootloader Control Block' (BCB) is a well established term/acronym in the Android namespace which refers to a location in a dedicated raw (i.e. FS-unaware) flash (e.g. eMMC) partition, usually called "misc", which is used as media for exchanging messages between Android userspace (particularly recovery [1]) and an Android-capable bootloader. On higher level, this allows implementing a subset of Android Bootloader Requirements [2], amongst which is the Android-specific bootloader flow [3]. Regardless how the latter is implemented in U-Boot ([3] being the most memorable example), reading/writing/dumping the BCB fields in the development process from inside the U-Boot is a convenient feature. Hence, make it available to the users. Some usage examples of the new command recorded on R-Car H3ULCB-KF ('>>>' is an overlay on top of the original console output): => bcb bcb - Load/set/clear/test/dump/store Android BCB fields Usage: bcb load <dev> <part> - load BCB from mmc <dev>:<part> bcb set <field> <val> - set BCB <field> to <val> bcb clear [<field>] - clear BCB <field> or all fields bcb test <field> <op> <val> - test BCB <field> against <val> bcb dump <field> - dump BCB <field> bcb store - store BCB back to mmc Legend: <dev> - MMC device index containing the BCB partition <part> - MMC partition index or name containing the BCB <field> - one of {command,status,recovery,stage,reserved} <op> - the binary operator used in 'bcb test': '=' returns true if <val> matches the string stored in <field> '~' returns true if <val> matches a subset of <field>'s string <val> - string/text provided as input to bcb {set,test} NOTE: any ':' character in <val> will be replaced by line feed during 'bcb set' and used as separator by upper layers => bcb dump command Error: Please, load BCB first! >>> Users must specify mmc device and partition before any other call => bcb load 1 misc => bcb load 1 1 >>> The two calls are equivalent (assuming "misc" has index 1) => bcb dump command 00000000: 62 6f 6f 74 6f 6e 63 65 2d 73 68 65 6c 6c 00 72 bootonce-shell.r 00000010: 79 00 72 00 00 00 00 00 00 00 00 00 00 00 00 00 y.r............. >>> The output is in binary/string format for convenience >>> The output size matches the size of inspected BCB field >>> (32 bytes in case of 'command') => bcb test command = bootonce-shell && echo true true => bcb test command = bootonce-shell- && echo true => bcb test command = bootonce-shel && echo true >>> The '=' operator returns 'true' on perfect match => bcb test command ~ bootonce-shel && echo true true => bcb test command ~ bootonce-shell && echo true true >>> The '~' operator returns 'true' on substring match => bcb set command recovery => bcb dump command 00000000: 72 65 63 6f 76 65 72 79 00 73 68 65 6c 6c 00 72 recovery.shell.r 00000010: 79 00 72 00 00 00 00 00 00 00 00 00 00 00 00 00 y.r............. >>> The new value is NULL-terminated and stored in the BCB field => bcb set recovery "msg1:msg2:msg3" => bcb dump recovery 00000040: 6d 73 67 31 0a 6d 73 67 32 0a 6d 73 67 33 00 00 msg1.msg2.msg3.. 00000050: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00000060: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ >>> --- snip --- >>> Every ':' is replaced by line-feed '\n' (0xA).

2019-07-11include: android_bootloader_message.h: Minimize the diff to AOSPEugeniu Rosca
Perform the following updates: - Relocate the commit id from the file to the description of U-Boot commit. The AOSP commit is c784ce50e8c10eaf70e1f97e24e8324aef45faf5. This is done to avoid stale references in the file itself. The reasoning is in https://patchwork.ozlabs.org/patch/1098056/#2170209. - Minimize the diff to AOSP, to decrease the effort of the next AOSP backports. The background can be found in: https://patchwork.ozlabs.org/patch/1080394/#2168454. - Guard the static_assert() calls by #ifndef __UBOOT__ ... #endif, to avoid compilation failures of files including the header.
