[U-Boot] [PATCH] mpc52xx, digsy_mtc_rev5: Fix Linux crash, if no Flash in bank 2
by Heiko Schocher 21 Mar '11

21 Mar '11

If no Flash is connected to cs1, Linux crashes, because reg entries are not correct adapted. Following fix is needed: - swap base addresses in CONFIG_SYS_FLASH_BANKS_LIST, as flash bank 1 is on chipselect 0 and flash bank 2 on chipselect 1 - call fdt_fixup_nor_flash_size() from ft_board_setup() Signed-off-by: Heiko Schocher <hs(a)denx.de> cc: Wolfgang Denk <hs(a)denx.de> cc: Werner Pfister <Pfister_Werner(a)intercontrol.de> cc: Detlev Zundel <dzu(a)denx.de> --- board/digsy_mtc/digsy_mtc.c | 5 +++++ include/configs/digsy_mtc.h | 4 ++-- 2 files changed, 7 insertions(+), 2 deletions(-) diff --git a/board/digsy_mtc/digsy_mtc.c b/board/digsy_mtc/digsy_mtc.c index afb0948..cbfdc9e 100644 --- a/board/digsy_mtc/digsy_mtc.c +++ b/board/digsy_mtc/digsy_mtc.c @@ -46,6 +46,7 @@ #include "is42s16800a-7t.h" #endif #include <libfdt.h> +#include <fdt_support.h> DECLARE_GLOBAL_DATA_PTR; @@ -415,6 +416,10 @@ void ft_board_setup(void *blob, bd_t *bd) ft_delete_node(blob, "mc,rv3029c2"); #endif #if defined(CONFIG_SYS_UPDATE_FLASH_SIZE) +#ifdef CONFIG_FDT_FIXUP_NOR_FLASH_SIZE + /* Update reg property in all nor flash nodes too */ + fdt_fixup_nor_flash_size(blob); +#endif ft_adapt_flash_base(blob); #endif } diff --git a/include/configs/digsy_mtc.h b/include/configs/digsy_mtc.h index bfbec6a..e7fd0f7 100644 --- a/include/configs/digsy_mtc.h +++ b/include/configs/digsy_mtc.h @@ -268,8 +268,8 @@ #define CONFIG_SYS_FLASH_BASE 0xFE000000 #define CONFIG_SYS_FLASH_BASE_CS1 0xFC000000 #define CONFIG_SYS_MAX_FLASH_BANKS 2 -#define CONFIG_SYS_FLASH_BANKS_LIST { CONFIG_SYS_FLASH_BASE_CS1, \ - CONFIG_SYS_FLASH_BASE} +#define CONFIG_SYS_FLASH_BANKS_LIST { CONFIG_SYS_FLASH_BASE, \ + CONFIG_SYS_FLASH_BASE_CS1} #define CONFIG_SYS_UPDATE_FLASH_SIZE #define CONFIG_FDT_FIXUP_NOR_FLASH_SIZE #else -- 1.7.3.4

[U-Boot] [PATCH v2] DA8xx: fix LPSC numbering
by Laurence Withers 21 Mar '11

21 Mar '11

The DA8xx chips have two modules PSC0 and PSC1 for the local power and sleep controllers (LPSC). Each LPSC has up to 32 submodules over which it has control, which are enumerated by the DAVINCI_LPSC_* symbols. This commit fixes the definitions of a number of symbols to be consistent with both the OMAP-L137 and OMAP-L138 data sheets (TI documents SPRS563D and SPRS586A respectively): some minor renaming to reflect actual functionality and some reordering of modules in PSC1 to be correct. None of the affected symbols were actually used anywhere in the code, so there are no related code changes.

[U-Boot] cfi_flash - bug with flash banks with different sector numbers
by Martin Krause 21 Mar '11

21 Mar '11

Hi list, I encountered a problem with the cfi_flash driver on a board with two flash banks with a different number of flash secotrs. It seems that the function find_sector() which tries to speed up successive flash accesses does not take into account the current flash bank correctly. I created a patch with a fix (see blow), but since I do not work with current U-Boot, this patch likely will not apply cleanly to TOT (but is neccessary, since the bug is still present there). Best regards, Martin >From 22454f09e058a3b0b8e86bc4d5566c21e23f5b63 Mon Sep 17 00:00:00 2001 From: Martin Krause <martin.krause(a)tqs.de> Date: Mon, 21 Mar 2011 13:08:19 +0100 Subject: [PATCH] cfi_flash: fix bug with flash banks with different sector numbers The function find_sector() does not take into account if the flash bank has changed since the last call. This could lead to illegal accesses inside and beyond the flash_info_t info strcture. For example if the current flash bank has less sectors than the last used flash bank. This patch adds two cheks. One that insures, that the current sector does not exceed the allowed maximum (which is always a good idea). And one that checks if the current access is to the same flash bank as the last access. If not, the search loop will start with sector 0.

[U-Boot] Changing USB speed from slow to fast
by Nikhilesh Dwivedi 21 Mar '11

21 Mar '11

Hi, I am working on ARM at91sam9g20ek. I am copying my Kernel image and rootfilesystem (jffs2) from USB to nand memory in UBOOT. Currently copying files from USB to RAM takes more time and I figured out from the code that USB Speed is low (1.5Mb/s). How can I change it to Fast speed in Uboot? Thanks for help. Regards, Nikhilesh Dwivedi

[U-Boot] [PATCH v2] UBI: Fix error code handling in ubi commands
by Stefan Roese 21 Mar '11

21 Mar '11

Some ubi commands returned negative error codes, resulting in the following error message on the prompt: "exit not allowed from main input shell." Negative error codes are not allowed. This patch now changes the UBI code to return positive error codes. Additionally "better" error codes are used, for example "ENOMEM" when no memory is available for the UBI volume creation any more. Also the output of some commands is enhanced: Before: => ubi read 100000 testvol 100000 Volume testvol found at volume id 0 read 1048576 bytes from volume 0 to 100000(buf address) => ubi write 100000 testvol 1000 Volume testvol found at volume id 0 After: => ubi read 100000 testvol 100000 Read 1048576 bytes from volume testvol to 00100000 => ubi write 100000 testvol 1000 4096 bytes written to volume testvol Signed-off-by: Stefan Roese <sr(a)denx.de> Cc: Wolfgang Denk <wd(a)denx.de> --- v2: - More negative return codes replaced - Enhancements to some command outputs - Common code extraced into function ubi_find_volume() to reduce code size common/cmd_ubi.c | 137 +++++++++++++++++++++++++---------------------------- 1 files changed, 65 insertions(+), 72 deletions(-) diff --git a/common/cmd_ubi.c b/common/cmd_ubi.c index b486ca8..629758f 100644 --- a/common/cmd_ubi.c +++ b/common/cmd_ubi.c @@ -123,7 +123,7 @@ static int ubi_info(int layout) static int verify_mkvol_req(const struct ubi_device *ubi, const struct ubi_mkvol_req *req) { - int n, err = -EINVAL; + int n, err = EINVAL; if (req->bytes < 0 || req->alignment < 0 || req->vol_type < 0 || req->name_len < 0) @@ -136,8 +136,11 @@ static int verify_mkvol_req(const struct ubi_device *ubi, if (req->alignment == 0) goto bad; - if (req->bytes == 0) + if (req->bytes == 0) { + printf("No space left in UBI device!\n"); + err = ENOMEM; goto bad; + } if (req->vol_type != UBI_DYNAMIC_VOLUME && req->vol_type != UBI_STATIC_VOLUME) @@ -151,13 +154,13 @@ static int verify_mkvol_req(const struct ubi_device *ubi, goto bad; if (req->name_len > UBI_VOL_NAME_MAX) { - err = -ENAMETOOLONG; + printf("Name too long!\n"); + err = ENAMETOOLONG; goto bad; } return 0; bad: - printf("bad volume creation request"); return err; } @@ -191,34 +194,39 @@ static int ubi_create_vol(char *volume, int size, int dynamic) return ubi_create_volume(ubi, &req); } -static int ubi_remove_vol(char *volume) +static struct ubi_volume *ubi_find_volume(char *volume) { - int i, err, reserved_pebs; - int found = 0, vol_id = 0; struct ubi_volume *vol = NULL; + int i; for (i = 0; i < ubi->vtbl_slots; i++) { vol = ubi->volumes[i]; - if (vol && !strcmp(vol->name, volume)) { - printf("Volume %s found at valid %d\n", volume, i); - vol_id = i; - found = 1; - break; - } + if (vol && !strcmp(vol->name, volume)) + return vol; } - if (!found) { - printf("%s volume not found\n", volume); - return -ENODEV; - } - printf("remove UBI volume %s (id %d)\n", vol->name, vol->vol_id); + + printf("Volume %s not found!\n", volume); + return NULL; +} + +static int ubi_remove_vol(char *volume) +{ + int err, reserved_pebs, i; + struct ubi_volume *vol; + + vol = ubi_find_volume(volume); + if (vol == NULL) + return ENODEV; + + printf("Remove UBI volume %s (id %d)\n", vol->name, vol->vol_id); if (ubi->ro_mode) { printf("It's read-only mode\n"); - err = -EROFS; + err = EROFS; goto out_err; } - err = ubi_change_vtbl_record(ubi, vol_id, NULL); + err = ubi_change_vtbl_record(ubi, vol->vol_id, NULL); if (err) { printf("Error changing Vol tabel record err=%x\n", err); goto out_err; @@ -231,8 +239,8 @@ static int ubi_remove_vol(char *volume) } kfree(vol->eba_tbl); - ubi->volumes[vol_id]->eba_tbl = NULL; - ubi->volumes[vol_id] = NULL; + ubi->volumes[vol->vol_id]->eba_tbl = NULL; + ubi->volumes[vol->vol_id] = NULL; ubi->rsvd_pebs -= reserved_pebs; ubi->avail_pebs += reserved_pebs; @@ -249,56 +257,46 @@ static int ubi_remove_vol(char *volume) return 0; out_err: - ubi_err("cannot remove volume %d, error %d", vol_id, err); + ubi_err("cannot remove volume %s, error %d", volume, err); + if (err < 0) + err = -err; return err; } static int ubi_volume_write(char *volume, void *buf, size_t size) { - int i = 0, err = -1; + int err = 1; int rsvd_bytes = 0; - int found = 0; struct ubi_volume *vol; - for (i = 0; i < ubi->vtbl_slots; i++) { - vol = ubi->volumes[i]; - if (vol && !strcmp(vol->name, volume)) { - printf("Volume \"%s\" found at volume id %d\n", volume, i); - found = 1; - break; - } - } - if (!found) { - printf("%s volume not found\n", volume); - return 1; - } + vol = ubi_find_volume(volume); + if (vol == NULL) + return ENODEV; + rsvd_bytes = vol->reserved_pebs * (ubi->leb_size - vol->data_pad); if (size < 0 || size > rsvd_bytes) { - printf("rsvd_bytes=%d vol->reserved_pebs=%d ubi->leb_size=%d\n", - rsvd_bytes, vol->reserved_pebs, ubi->leb_size); - printf("vol->data_pad=%d\n", vol->data_pad); - printf("Size > volume size !!\n"); - return 1; + printf("size > volume size!
