[U-Boot] [PATCH 2/2 v9] ARM : Add support for MINI2440 (s3c2440).
Gabriel Huau
contact at huau-gabriel.fr
Mon Apr 30 16:11:53 CEST 2012
Support of the MINI2440 board from FriendlyARM from
an old version of u-boot :
http://repo.or.cz/r/u-boot-openmoko/mini2440.git
Currently, supporting only boot from NOR.
Signed-off-by: Gabriel Huau <contact at huau-gabriel.fr>
---
Changes for v2:
- Coding style cleanup
- Remove unnecessary files modification
- Remove unnecessary board configuration set
Changes for v3:
- Coding style cleanup
- Move some macro definition from lowlevel_init.S
to a new header
- Remove some "magic bloat" with I/O board initialization
- Add a pll_delay and replace loop by it
- Somme cleanup in the configuration file
- Cancel modifications on an SoC specific header
- Add my name to copyright
Changes for v4:
- Move dram init to dram_init() instead low_levelinit
- Remove u -boot env from configuration file and change
the address of initial SP
- Remove PLL init, now it's SoC specific
Changes for v5:
- Clean up configuration file
- Add a MAINTAINERS entry
- Add a README.mini2440 file
- Use gpio/iomux interface in case of magic numbers
- Use get_ram_size()
Changes for v6:
- Coding style cleanup
- Remove some unused define in the board config
Changes for v7:
- Cleanup coding style
- Changement of the commit message
Changes for v8:
- Replace define[tab] by define[space]
Changes for v9:
- Add a nice commit message

+U-Boot for FriendlyARM Mini2440 (s3c2440)
+
+This file contains information for the port of U-Boot to FriendlyARM
+mini2440
+
+All information about the board can be found on :
+http://www.friendlyarm.net/products/mini2440
+
+To build u-boot : ./MAKEALL mini2440
+
+Overview :
+--------
+FriendlyARM Mini 2440 SBC (Single-Board Computer) with 400 MHz Samsung S3C2440
+ARM9 processor. The board measures 100 x 100 mm, ideal for learning about ARM9
+systems. It's a low cost board.
+
+Boot Methods :
+------------
+Mini2440 can boot from NOR or NAND.
+
+Build :
