===================================================================
======================================================================
Changes for U-Boot 1.1.2 for aESOP-2440
======================================================================
* Add SD-card initialize/read/write by Salamander, 19 Jun 2005
- Fix SDIDAT register bug (8bit -> 32bit) in /include/s3c24x0.h
- Add sd.c & sd.h in /board/aesop2440
- Modify aesop2440.c to show SDcard status
* USB mass storage class interface to SD-card by jeenspa(6-July-2005)
* Linux booting from NAND flash file system(yaffs) by jeenspa(6-July-2005).
* DOS-FAT file I/O for SD-card by Salamander(8-July-2005)
======================================================================
To Do list
======================================================================
* LCD_printf() function implementaion for SD-file list show.
* Key input function for file select and execute.
* Unicode display for VFAT file name.
* Linux booting from SD file system.
======================================================================
Tips
======================================================================
* Temporary modification of config.mk should be applied for debugging.
- If TEXT_BASE is 0x33C00000 in NOR-flash U-boot, change it to 0x33800000.
- With this temporary change, you can download u-boot via TFTP for development.
* How to change spalsh logo
- prepare a 480x272 24bpp bmp file(true color bitmap file without palette)
- convert bmp to simple C header file (ex. xxd -i logo01.bmp > aesop-logo-02.h)
- compile and enjoy your own splash screen.
