The "dm" command under CONFIG_CMD_DM should live under cmd/ rather than test/dm/ so move it.

[U-Boot] [PATCH 1/1] tee: change return code for REE FS supplicant cmd
by Igor Opaniuk 17 Dec '18

17 Dec '18

If OP-TEE core is compiled with support of REE FS and RPMB at the same time (CFG_RPMB_FS ?= y; CFG_RPMB_FS ?= y), and persistent storage API is used with TEE_STORAGE_PRIVATE storage id, it will lead to TA panic. E/TC:? 0 TA panicked with code 0xffff0009 ..... E/TC:? 0 Call stack: E/TC:? 0 0x000000004002f2f8 TEE_OpenPersistentObject at lib/libutee/tee_api_objects.c:422 In this particular case TEE_ERROR_STORAGE_NOT_AVAILABLE is more suitable than TEE_ERROR_NOT_IMPLEMENTED, as it provides to a TA a possibility to handle this error code [1]. >From GPD TEE Internal Core specification [2]: TEE_ERROR_STORAGE_NOT_AVAILABLE - if the persistent object is stored in a storage area which is currently inaccessible. It may be associated with the device but unplugged, busy, or inaccessible for some other reason.

[U-Boot] MIPS (mt7688): EBase change in U-Boot breaks Linux
by Stefan Roese 17 Dec '18

17 Dec '18

Hi! I've been hunting for a problem for quite some time, where Linux hangs / crashes in userspace at some point on my MT7688 based systems. I found that this problem can be avoided (worked around) by not giving Linux the full memory (by using DT memory node fixup or mem= kernel cmdline). When reducing this memory by the memory used by U-Boot (stack pointer minus some KiB value as this is the "lowest" memory used by U-Boot), then Linux runs just fine. My first idea here was, that this issue is cache related (most likely I-cache). But all tests and debugging in this area did not fix this issue (even running with caches disabled). Finally I found that this line in U-Boot makes Linux break: arch/mips/lib/traps.c: void trap_init(ulong reloc_addr) unsigned long ebase = gd->irq_sp; ... write_c0_ebase(ebase); This sets EBase to something like 0x87e9b000 on my system (128MiB). And Linux then re-uses this value and copies the exceptions handlers to this address, overwriting random code and leading to an unstable system. So my questions now is, how should this be handled on the MT7688 platform instead? One way would be to set EBase back to the original value (0x80000000) before booting into Linux. Another solution would be to add some Linux code like board_ebase_setup() to the MT7688 Linux port. Since I'm still no real MIPS expert yet, I would really like to get some advise here on how to best solve this issue. Maybe I missed something. Comments? Thanks, Stefan

[U-Boot] [PATCH] sunxi: Allow booting from 128KB SD/eMMC offset
by Andre Przywara 17 Dec '18

17 Dec '18

On modern Allwinner SoCs (tested: H2+, A64, H5, H6) the BootROM can actually load the SPL also from sector 256 (128KB) of an SD card or eMMC chip. For more details, see [1]. In this case the boot source indicator (written at offset 0x28 of SRAM A1) has bit 4 set, so it's 0x10 for SD card and 0x12 for eMMC. Add those new values to the existing boot source check to allow booting the SPL from those "high" disk offsets as well. For this to work, the value of CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR needs to be adjusted, for instance to 0x140 (right after the high SPL). Doing this dynamically sounds desirable, but looks nasty to implement.

[U-Boot] [RFC PATCH v1 0/7] ARM: kirkwood: migration to DM_USB
by Chris Packham 17 Dec '18

17 Dec '18

This is my initial series to convert the kirkwood platforms to DM_USB. I've been testing on an old kirkwood eval board which patch 2 adds. I've got some problems related to DMA which I think are probably due to caching or have something to do with the Z0 rev of the CPU. I'd really appreciate some testing on other kirkwood platforms.
