* GCC47: Fix warning in cmd_nand.cMarek Vasut2012-04-291-1/+1

* Convert cmd_usage() calls in common to use a return valueSimon Glass2012-03-061-3/+3
| | | | | | | | | Change all files in common/ to use CMD_RET_USAGE instead of calling cmd_usage() directly. I'm not completely sure about this patch since the code since impact is small (100 byte or so on ARM) and it might need splitting into smaller patches. But for now here it is.

* cmd_nand.c: Fix 'nand dump' after latest MTD resyncTom Rini2012-02-281-2/+3
| | | | | | | | | | | | | | With 2a8e0fc nand_do_read_ops changed in behavior slightly (keeping in sync with the kernel which did this change in b64d39d8) such that the OOB data is always copied into oobbuf and never appended to datbuf. Within U-Boot only the nand_dump function (for the dump nand subcommand) was expecting the OOB data to only be appended to datbuf. So we now change nand_dump to not malloc extra space, correct the comment about datbuf and OOB data and switch the pointer to oobbuf before printing.

* cmd_nand: add nand write.trimffs commandBen Gardiner2011-07-011-0/+16
| | | | | | | | | | | | | | | | | | Add another nand write. variant, trimffs. This command will request of nand_write_skip_bad() that all trailing all-0xff pages will be dropped from eraseblocks when they are written to flash as-per the reccommended behaviour of the UBI FAQ [1]. The function that implements this timming is the drop_ffs() function by Artem Bityutskiy, ported from the mtd-utils tree.

Convert the only flag currently passed to the nand_write_ skip_bad() function to a bitfield of only one allocated member. This should avoid an explosion of int's at the end of the parameter list or the ambiguous calls like nand_write_skip_bad(info, offset, len, buf, 0, 1, 1); nand_write_skip_bad(info, offset, len, buf, 0, 1, 0); Instead there will be: nand_write_skip_bad(info, offset, len, buf, WITH_YAFFS_OOB | WITH_OTHER); Signed-off-by: Ben Gardiner <bengardiner@nanometrics.ca> Acked-by: Detlev Zundel <dzu@denx.de> Signed-off-by: Scott Wood <scottwood@freescale.com>

* nand erase: .spread, .part, .chip subcommandsScott Wood2010-10-111-6/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A while back, in http://lists.denx.de/pipermail/u-boot/2009-June/054428.html, Michele De Candia posted a patch to not count bad blocks toward the requested size to be erased. This is desireable when you're passing in something like $filesize, but not when you're trying to erase a partition. Thus, a .spread subcommand (named for consistency with http://lists.denx.de/pipermail/u-boot/2010-August/075163.html) is introduced to make explicit the user's desire to erase for a given amount of data, rather than to erase a specific region of the chip. While passing $filesize to "nand erase" is useful, accidentally passing something like $fliesize currently produces quite unpleasant results, as the variable evaluates to nothing and U-Boot assumes that you want to erase the entire rest of the chip/partition. To improve the safety of the erase command, require the user to make explicit their intentions by using a .part or .chip subcommand. This is an incompatible user interface change, but keeping compatibility would eliminate the safety gain, and IMHO it's worth it. While touching nand_erase_opts(), make it accept 64-bit offsets and sizes, fix the percentage display when erase length is rounded up, eliminate an inconsistent warning about rounding up the erase length which only happened when the length was less than one block (rounding up for $filesize is normal operation), and add a diagnostic if there's an attempt to erase beginning at a non-block boundary.

* cmd_nand: some infrastructure fixes and refactoringScott Wood2010-10-111-107/+167
| | | | | | | | | | | | | | | | - If the current device is overridden by a named partition, - update the caller's pointer/index, rather than copy over the nand_info struct, and - be sure to call board_nand_select_device even when the device is overridden by a named partition. - Support 64-bit offsets/sizes in a few more places. - Refactor arg_off_size for added readability and flexibility, and some added checks such as partition size. - Remove redundant check for bad subcommands -- if there's no match it'll print usage when it gets to the end anyway.

* NAND: environment offset in OOB (CONFIG_ENV_OFFSET_OOB)Ben Gardiner2010-07-121-1/+106
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a re-submission of the patch by Harald Welte <laforge@openmoko.org> with minor modifications for rebase and changes as suggested by Scott Wood <scottwood@freescale.com> [1] [2]. This patch enables the environment partition to have a run-time dynamic location (offset) in the NAND flash. The reason for this is simply that all NAND flashes have factory-default bad blocks, and a fixed compile time offset would mean that sometimes the environment partition would live inside factory bad blocks. Since the number of factory default blocks can be quite high (easily 1.3MBytes in current standard components), it is not economic to keep that many spare blocks inside the environment partition. With this patch and CONFIG_ENV_OFFSET_OOB enabled, the location of the environment partition is stored in the out-of-band (OOB) data of the first block in flash. Since the first block is where most systems boot from, the vendors guarantee that the first block is not a factory default block. This patch introduces the 'nand env.oob' command, which can be called from the u-boot command line. 'nand env.oob get' reads the address of the environment partition from the OOB data, 'nand env.oob set {offset,partition-name}' allows the setting of the marker by specifying a numeric offset or a partition name.

* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-041-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make sure the compiler can check that no such modifications are being done by changing the code into "char * const argv[]". This modification is the result of debugging a strange crash caused after adding a new command, which used the following argument processing code which has been working perfectly fine in all Unix systems since version 6 - but not so in U-Boot: int main (int argc, char **argv) { while (--argc > 0 && **++argv == '-') { /* ====> */ while (*++*argv) { switch (**argv) { case 'd': debug++; break; ... default: usage (); } } } ... } The line marked "====>" will corrupt the malloc data structures and usually cause U-Boot to crash when the next command gets executed by the shell. With the modification, the compiler will prevent this with an error: increment of read-only location '*argv' N.B.: The code above can be trivially rewritten like this: while (--argc > 0 && **++argv == '-') { char *arg = *argv; while (*++arg) { switch (*arg) { ...

| | | | | | | | | | | | | Legacy NAND had been scheduled for removal. Any boards that use this were already not building in the previous release due to an #error. The disk on chip code in common/cmd_doc.c relies on legacy NAND, and it has also been removed.

Commit ``Make "usage" messages more helpful.'' changed this partially. But it also became clear that lots of "Usage" and "Help" messages (fields "usage" and "help" in struct cmd_tbl_s respective) were actually redundant.
