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
<etienne.carriere@stericsson.com> 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.
