[U-Boot] [PATCH v2 11/11] New board support: Nokia RX-51 aka N900

Pali Rohár pali.rohar at gmail.com
Sat Apr 28 19:26:51 CEST 2012


This board definition results in a u-boot.bin which can be chainloaded
from NOLO in qemu or on a real N900. It does very little hardware config
because NOLO has already configured the board. Only needed is enabling
internal eMMC memory via twl4030 regulator which is not enabled by NOLO.

NOLO is expecting a kernel image and will treat any image it finds in
onenand as such. This u-boot is intended to be flashed to the N900 like
a kernel. In order to transparently boot the original kernel, it will be
appended to u-boot.bin at 0x40000. NOLO will load the entire image into
memory and execute u-boot, which saves the ATAGs set by NOLO. Then the
bootscripts will attempt to load uImage or boot.scr from a fat or ext2
filesystem in external SD card or internal eMMC memory. If this fails
or keyboard is closed the appended kernel image will be booted using the
stored ATAGs (see boot order).

There is support for hardware watchdog. It is started by NOLO so u-boot
must kick watchdog to prevent reboot device (but not very often, max
every 2 seconds). There is also support for framebuffer display output
with ANSI espace codes and the N900 HW keyboard input. USB tty works but
is disabled because it prevents the current Maemo kernel from booting.

Based on previous work by: Alistair Buxton <a.j.buxton at gmail.com>

Default boot order:

 * 0. if keyboard is closed boot automatically attached kernel image
 * 1. try boot from external SD card
 * 2. try boot from internal eMMC memory
 * 3. try boot from attached kernel image

Boot from SD or eMMC in this order:

 * find boot.scr on first fat partition
 * find uImage on first fat parition
 * same order for 2. - 4. fat partition

 * find boot.scr on first ext2 partition
 * find uImage on first ext2 parition
 * same order for 2. - 4. ext2 partition

Available additional commands/variables:

 * run sercon - Use serial port for control
 * run usbcon - Use usbtty for control
 * run vgacon - Use framebuffer and HW keyboard for control (default)

 * run sdboot - Boot from external SD card (see boot order)
 * run emmcboot - Boot from internal eMMC memory (see boot order)
 * run attachboot - Boot attached kernel image (attached to U-Boot binary)

 * run scriptload - Load boot script ${mmcscriptfile}
 * run scriptboot - Run loaded boot script
 * run kernload - Load kernel image ${mmckernfile}
 * run initrdload - Load initrd image ${mmcinitrdfile}
 * run kernboot - Boot loaded kernel image
 * run kerninitrdboot - Boot loaded kernel image with loaded initrd image

 * run trymmcscriptboot - Try to load and boot script ${mmcscriptfile}
 * run trymmckernboot - Try to load and boot kernel image ${mmckernfile}
 * run trymmckerninitrdboot - Try to load and boot kernel image ${mmckernfile}
                              with initrd image ${mmcinitrdfile}

Variables for loading files from mmc:

 * mmc ${mmcnum} (0 - external, 1 - internal)
 * partition number ${mmcpart} (1 - 4)
 * parition type ${mmctype} (fat, ext2)

Changes since v1:
   - Set correct configs for Memory Map
   - Enable passing memory tag to kernel atags
   - Use gpio input command for detecting keyboard slide
   - Restore powerbus state after calling twl4030 regulator code
   - Renamed command noloboot to attachboot
   - Atag address must be always 0x80000100, removed code from lowlevel
   - Added usb vendor, product id and product name
   - Enabled command line editing
   - Fixed keymap and cursor keys

Changes since original version:
   - Removed Makefile targets: clean and distclean
   - Rewrited bootcommand and env variables in nokia_rx51.h
   - Removed useless CONFIG defines in nokia_rx51.h
   - Disable L2 cache with CONFIG_SYS_L2CACHE_OFF - fixed battery draining
   - Added onenand support (default disabled due to big u-boot size)
   - Moved inlined asm code to new file lowlevel_init.S
   - Fixed commit message
