From 20503b61a7f73fad8ee97219f7a1e74de3a8a2ac Mon Sep 17 00:00:00 2001 From: Michael Brandt Date: Tue, 20 Jul 2010 15:08:22 +0200 Subject: Read/write VFAT support from Rockbox-3.3 FAT stack Add read/write VFAT support from Rockbox-3.3 FAT stack. It should be also applicable to the unmodified 2009.11 U-Boot release. Note that is was taken as is from Rockbox and from a older U-Boot Rockbox patch. "checkpatch" shows very many coding style errors and warnings, but it is tedious work to clean this up. To make this patch work an additional mmc_block_write() board support routine and the errno variable are needed. Furthermore following defines in the board config header file: #define CONFIG_ROCKBOX_FAT 1 #define CONFIG_U_BOOT 1 #define CONFIG_SUPPORT_VFAT 1 #define CONFIG_CMD_TREE_FAT This will be added in a follow-up patch. This patch is based on the patch from Etienne Carriere for the U671x U-Boot: This commit adds FAT write support to u-boot native read-only FAT code. Commit initially applied on u-boot-v2009.01 (SHA1: 72d15e705bc3983884105cb7755c7ba80e74a0a5) Based on FAT stack dumped from Rockbox package v3.1 (www.rockbox.org). Based on initial Rockbox FAT stack integration in u-boot by Keith Outwater (outwater@comcast.net). Current porting is aligned with Rockbox v3.3 FAT stack. Enable upon config switches: CONFIG_CMD_FAT CONFIG_ROCKBOX_FAT CONFIG_CMD_TREE_FAT (recommended) CONFIG_SUPPORT_VFAT (recommended) C code APIs (from U-boot native FAT support): int fat_register_device(block_dev_desc_t *dev_desc, int part_no); long file_fat_read(const char *path, void *buf, unsigned long maxsize); int file_fat_ls(const char *dirname); int file_fat_detectfs(void); C code APIs (added by Rockbox FAT support): long file_fat_write(const char *path, void *buf, unsigned long maxsize); int file_fat_rm(const char *path); int file_fat_rmdir(const char *path); int file_fat_mkdir(const char *path); int file_fat_cd(const char *path); int file_fat_pwd(void); int file_fat_mv(const char *oldpath, const char *newpath); unsigned int rockbox_fat_free(unsigned long size_kbyte); unsigned int rockbox_fat_size(void); Use "help fat" from u-boot console to see available commands.
