[U-Boot] [PATCH v2] arm, davinci: cam_enc_4xx board updates

Heiko Schocher hs at denx.de
Tue Jan 17 08:20:09 CET 2012


- CONFIG_SYS_MMC_ENV_DEV, needed if environment on mmc
- wait for 1 second timer in board_late_init() only, if
  timer is running.
- add UBI/UBIFS support
- add FIT images support
- menu support
- U-Boot max size now 0xa0000
- SPL now Block 0 page 0
- new MTD partitioning
  0x00000000 SPL
  0x00020000 UBL-Header
  0x00040000 UBL-Header
  0x00060000 UBL-Header
  0x00080000 UBoot (0xa0000(U-Boot length) + 0x60000(3 spare blocks))
  0x00180000 ENV- Variablen (1)
  0x001a0000 ENV- Variablen (2)
  0x001c0000 ENV- Variablen (reserved for Bad Block)
  0x001e0000 ENV- Variablen (reserved for Bad Block)
  0x00200000 UBI-Device

  UBI Volumes:
  „default“:  contain environment-default values
  „rootfs1“:  UBIFS root-fs (1); contain linux kernel image
  „rootfs2“:  UBIFS root-fs (2); contain linux kernel image
  „data-ro“:  UBIFS data (read only)
  „data-rw“:  UBIFS data (read/write)

- new environment variables:
  - app_reset
    (this is only passed per cmdline to linux)
  - dvn_app_vers
    string from ramdisk description contained in the
    FIT image
  - dvn_boot_vers
    string from ubootimage description contained in the
    FIT image
  - saveparms, restoreparms, restoretmpparms, savetmpparms
    helper for saving network parameter.
  - ubiargs
    set ubi kernel cmdlinargs for booting with a ubifs rootfs
  - ubi_ubi boot with reading kernel image from ubifs, and
    use a ubifs as rootfs

- checkpatch shows no errors/warnings
- patches needed for this patch:

  - arm, davinci: add workaround for not resetting DMA bus and VPSS modules
    http://patchwork.ozlabs.org/patch/136155/
  - arm, davinci: add timer defines for tcr field
    http://patchwork.ozlabs.org/patch/136156/
  - common, menu: enhancements
    http://lists.denx.de/pipermail/u-boot/2012-January/115904.html
    patches:
    - common: add possibility for readline_into_buffer timeout
      http://patchwork.ozlabs.org/patch/136415
    - common, menu: add statusline support
      http://patchwork.ozlabs.org/patch/136417
    - common, menu: show menu on startup if CONFIG_MENU_SHOW is defined
      http://patchwork.ozlabs.org/patch/136418

- a "MAKEALL -a arm" compiles fine with this patches

- changes for v2:
  - rework as a result of a comment from Mike Frysinger:
    - menu_show get passed bootdelay, factor this in.
  - add comment from Wolfgang Denk:
    - use for FIT image type "firmware" and introduce a new
      "subtype" property, which contains the info, what sort
      of firmware the image is (ubl header, spl image, u-boot image
      or default environment). So following patch is not needed anymore:
        common, image: introduce new uimage types
        http://patchwork.ozlabs.org/patch/136157
  - add comment from Tom Rini <trini at ti.com>
    change comment in board/ait/cam_enc_4xx/ublimage.cfg
