2011-01-11Revert "boot cmds: convert to getenv_yesno() with autostart"Wolfgang Denk
This reverts commit 5a442c0addc69d0c4b58e98e5aec1cf07576debb. This commit changed the behaviour of getenv_yesno() (both the default behaviour and the documented behaviour for abbreviated arguments) which resulted in problems in several areas. Signed-off-by: Wolfgang Denk <wd@denx.de>

2010-10-18Fix warning in nand unlock commandScott Wood
Commit ea533c260a801c4e51f92f75165cebe6d7b01e35 changed arg_off_size to take a pointer to a device index, rather than to the device itself. When updating callers, the nand unlock code was missed. Signed-off-by: Scott Wood <scottwood@freescale.com>
2010-10-11nand commands: make only "dump" repeatable.Scott Wood
The dump command is made to increment its address on repeat, as md does. Other commands do not make sense to issue repeatedly, and can be irritating when it happens accidentally, so don't. Signed-off-by: Scott Wood <scottwood@freescale.com> Tested-by: Ben Gardiner <bengardiner@nanometrics.ca>
2010-10-11nand erase: .spread, .part, .chip subcommandsScott Wood
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.

2010-10-11cmd_nand: some infrastructure fixes and refactoringScott Wood
- 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.

2010-07-12NAND: environment offset in OOB (CONFIG_ENV_OFFSET_OOB)Ben Gardiner
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.

2010-07-04Make sure that argv[] argument pointers are not modified.Wolfgang Denk
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) { ...

2009-07-16Remove legacy NAND and disk on chip code.Scott Wood
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. There is newer disk on chip code in drivers/mtd/nand; someone with access to hardware and sufficient time and motivation can try to get that working, but for now disk on chip is not supported.

2009-07-07nand/onenand: Fix missing argument checking for "markbad" commandWolfgang Denk
The "nand markbad" and "onenand markbad" commands did not check if an argument was passed; if this was forgotten, no error was raised but block 0 was marked as bad. While fixing this bug, clean up the code a bit and allow to pass more than one block address, thus allowing to mark several blocks as bad in a single command invocation.

2009-06-12General help message cleanupWolfgang Denk
Many of the help messages were not really helpful; for example, many commands that take no arguments would not print a correct synopsis line, but "No additional help available." which is not exactly wrong, but not helpful either. 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. This patch cleans this up - for example: Before: => help dtt dtt - Digital Thermometer and Thermostat Usage: dtt - Read temperature from digital thermometer and thermostat. After: => help dtt dtt - Read temperature from Digital Thermometer and Thermostat Usage: dtt Signed-off-by: Wolfgang Denk <wd@denx.de>

2008-08-12Update MTD to that of Linux Juul
A lot changed in the Linux MTD code, since it was last ported from Linux to U-Boot. This patch takes U-Boot NAND support to the level of Linux and will enable support for very large NAND devices (4KB pages) and ease the compatibility between U-Boot and Linux filesystems. This patch is tested on two custom boards with PPC and ARM processors running YAFFS in U-Boot and Linux using gcc-4.1.2 cross compilers. MAKEALL ppc/arm has some issues: * DOC/OneNand/nand_spl is not building (I have not tried porting these parts, and since I do not have any HW and I am not familiar with this code/HW I think its best left to someone else.) Except for the issues mentioned above, I have ported all drivers necessary to run MAKEALL ppc/arm without errors and warnings. Many drivers were trivial to port, but some were not so trivial.
