[U-Boot] [PATCH 05/11] arm/pxa: fix environment location/length for vpac270 and related bugs.

[Mikhail Kshevetskiy]

Define MONITOR_BASE on the base of used flash type. Define ENV_ADDR as
MONITOR_BASE + MONITOR_LEN. Fix environment sector size (NOR: 32Kb for
first four sectors and 128Kb for other; OneNAND: 128Kb).

Last but not least: we have MONITOR_LEN = 0x40000, one sector for environment
and one sector for its redundancy copy (2 * 0x20000 = 256Kb). So the kernel
may start from 0x00080000 only.

[U-Boot] [PATCH 08/11] arm/pxa: increase CONFIG_SYS_MALLOC_LEN to (196Kb + space for environment)

[Mikhail Kshevetskiy]

it looks like u-boot allocates a buffer of CONFIG_ENV_SECT_SIZE
size when making "saveenv" command. In our case CONFIG_ENV_SECT_SIZE
is 128Kb, so having CONFIG_SYS_MALLOC_LEN = (128Kb + space for
environment) is not sufficient.

Increase CONFIG_SYS_MALLOC_LEN to (196Kb + space for environment) to
resolve a problem.

Good catch, but let's make it 0x60000 as spare env isn't used.

If CONFIG_ENV_OVERWRITE is #defined in your config
file, the write protection for vendor parameters is
completely disabled. Anybody can change or delete
these parameters.

I think that's ok. Anyone can remove it before deploying the real product.

You probably hit this because you changed the ENV size. Wolfgang, can you please

I don't think this makes sense on a real-life system, but then, I
don't know neither the hardware nor it's use cases.  If the board
maintainer claims that this is OK for all known use cases...

The space needed for malloc() depends on many things. Most systems
have sufficient RAM these days, so it makes little sense to be stingy
here.
