* ARM: mxs: Enable DCDC converter for battery bootMarek Vasut2013-10-31-0/+2
| | | | | | | | | | In case the board detected sufficient voltage for battery boot, make sure the DCDC converter is ON and the board is not running only from linregs, otherwise an instability will be observed.

* imx_watchdog: do not soft-reset while watchdog initAnatolij Gustschin2013-10-31-1/+2
| | | | | | | | Currently the driver clears WCR_SRS bit when enabling the watchdog and this causes a software reset. Do not clear WCR_SRS. Signed-off-by: Anatolij Gustschin <agust@denx.de>
* ARM: mxs: Setup stack in JTAG modeMarek Vasut2013-10-17-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | In case the MX23/MX28 is switched into JTAG mode via the BootMode select switches, the BootROM bypasses the CPU core registers initialization. This in turn means that the Stack Pointer (SP) register is not set as it is in every other mode of operation, but instead is only zeroed out. To prevent U-Boot SPL from crashing in this obscure JTAG mode, configure the SP to point at the CONFIG_SYS_INIT_SP_ADDR if the SP is zeroed out. Note that in case the SP is already configured, we must preserve that exact SP value and must not modify it. This is important since in every other mode but the JTAG mode, the SPL returns into the BootROM and BootROM in turn loads U-Boot itself. If the SP were to be corrupted, the BootROM won't be able to continue it's operation after returned from SPL and the system would crash. Finally, add the JTAG mode switch identifier, so it's not recognised as Unknown mode.

Commit d7884e047d08447dfd1374e9fa2fdf7ab36e56f5 does not go far enough. There is still at least one call chain that can result in a crash. The do_tftpb(), do_ext2load(), and do_get_fat() functions expect a valid cmdtp. Passing in NULL is particularly bad in the do_tftpb() case, because eventually boot_get_kernel() will be called with a NULL cmdtp: do_tftpb() -> netboot_common() -> bootm_maybe_autostart() -> do_bootm() -> do_bootm_states() -> bootm_find_os() -> boot_get_kernel() Around line 991 in cmd_bootm.c, boot_get_kernel() will dereference the null pointer, and the board will crash.

For example, you may split a root filesystem UBIFS image into parts, provide the total size of the image to the first write.part command and then use multiple write.part commands to write the subsequent parts of the volume. This results in a sequence of commands akin to: ext4load mmc 0:1 0x80000000 rootfs.ubifs.0 ubi write.part 0x80000000 root 0x08000000 0x18000000 ext4load mmc 0:1 0x80000000 rootfs.ubifs.1 ubi write.part 0x80000000 root 0x08000000 ext4load mmc 0:1 0x80000000 rootfs.ubifs.2 ubi write.part 0x80000000 root 0x08000000 This would write 384MiB of data to the UBI volume 'root' whilst only requiring 128MiB of said data to be held in memory at a time.

The effect is that calls to mtd_read will not return -EUCLEAN if the number of ECC-corrected bit errors is below a certain threshold, which defaults to the strength of the ECC. This allows -EUCLEAN to stop indicating "some bits were corrected" and begin indicating "a large number of bits were corrected, the data held in this region of flash may be lost soon". UBI makes use of this and when -EUCLEAN is returned from mtd_read it will move data to another block of flash. Without adopting this interface change UBI on U-boot attempts to move data between blocks every time a single bit is corrected using the ECC, which is a very common occurance on some devices. For some devices where bit errors are common enough, UBI can get stuck constantly moving data around because each block it attempts to use has a single bit error. This condition is hit when wear_leveling_worker attempts to move data from one PEB to another in response to an -EUCLEAN/UBI_IO_BITFLIPS error. When this happens ubi_eba_copy_leb is called to perform the data copy, and after the data is written it is read back to check its validity. If that read returns UBI_IO_BITFLIPS (in response to an MTD -EUCLEAN) then ubi_eba_copy_leb returns 1 to wear_leveling worker, which then proceeds to schedule the destination PEB for erasure. This leads to erase_worker running on the PEB, and following a successful erase wear_leveling_worker is called which begins this whole cycle all over again. The end result is that (without UBI debug output enabled) the boot appears to simply hang whilst in reality U-boot busily works away at destroying a block of the NAND flash. Debug output from this situation: UBI DBG: ensure_wear_leveling: schedule scrubbing UBI DBG: wear_leveling_worker: scrub PEB 1027 to PEB 4083 UBI DBG: ubi_io_read_vid_hdr: read VID header from PEB 1027 UBI DBG: ubi_io_read: read 4096 bytes from PEB 1027:4096 UBI DBG: ubi_eba_copy_leb: copy LEB 0:0, PEB 1027 to PEB 4083 UBI DBG: ubi_eba_copy_leb: read 1040384 bytes of data UBI DBG: ubi_io_read: read 1040384 bytes from PEB 1027:8192 UBI: fixable bit-flip detected at PEB 1027 UBI DBG: ubi_io_write_vid_hdr: write VID header to PEB 4083 UBI DBG: ubi_io_write: write 4096 bytes to PEB 4083:4096 UBI DBG: ubi_io_read_vid_hdr: read VID header from PEB 4083 UBI DBG: ubi_io_read: read 4096 bytes from PEB 4083:4096 UBI DBG: ubi_io_write: write 4096 bytes to PEB 4083:8192 UBI DBG: ubi_io_read: read 4096 bytes from PEB 4083:8192 UBI: fixable bit-flip detected at PEB 4083 UBI DBG: schedule_erase: schedule erasure of PEB 4083, EC 55, torture 0 UBI DBG: erase_worker: erase PEB 4083 EC 55 UBI DBG: sync_erase: erase PEB 4083, old EC 55 UBI DBG: do_sync_erase: erase PEB 4083 UBI DBG: sync_erase: erased PEB 4083, new EC 56 UBI DBG: ubi_io_write_ec_hdr: write EC header to PEB 4083 UBI DBG: ubi_io_write: write 4096 bytes to PEB 4083:0 UBI DBG: ensure_wear_leveling: schedule scrubbing UBI DBG: wear_leveling_worker: scrub PEB 1027 to PEB 4083 ... This patch adopts the interface change as in Linux commit edbc4540 in order to avoid such situations. Given that none of the drivers under drivers/mtd return -EUCLEAN, this should only affect those using software ECC. I have tested that it works on a board which is currently out of tree, but which I hope to be able to begin upstreaming soon.

Thus this patch ensures that the reserved bit is not accesssed. It has been observed that some USB devices will fail to enumerate with errors such as 'error in inquiry' without this patch.
