14 years agoNAND: environment offset in OOB (CONFIG_ENV_OFFSET_OOB)
Ben Gardiner [Mon, 5 Jul 2010 17:27:07 +0000 (13:27 -0400)]
NAND: environment offset in OOB (CONFIG_ENV_OFFSET_OOB)

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.

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;

Background Info:
Some PPC440/460 boards have caches enabled in the Boot/FLASH TLB (via
init.S) to speed up the boot process. In relocate_code (start.S) the

needed for the CFI FLASH driver.

This patch now cleans this code up:
- CONFIG_SYS_TLB_FOR_BOOT_FLASH is defined to 0 (default TLB) if not
  defined in the top of this file. This way, we can remove an ugly
  #ifdef in this code.
- Replace complex "#if defined(CONFIG_440EP) || defined(CONFIG_GR)..."
