mpc85xx, mpc86xx: Fix gd->cpu pointer after relocation

2009-12-15T21:45:51+00:00

The gd->cpu pointer is set to an address located in flash when the
probecpu() function is called while U-Boot is executing from flash.
This pointer needs to be updated to point to an address in RAM after
relocation has occurred otherwise Linux may not be able to boot due to
"fdt board" crashing if flash has been erased or changed.

This bug was introduced in commit
a0e2066f392782730f0398095e583c87812d97f2.

MVBLUE: Remove CONFIG_CMD_IRQ

2009-12-14T20:31:17+00:00

Neither the MVBLUE nor its underlying architecture implement the
do_irqinfo() function which is required when CONFIG_CMD_IRQ is defined.
This change fixes the following MVBLUE compiler error:

-> ./MAKEALL MVBLUE
Configuring for MVBLUE board...
common/libcommon.a(cmd_irq.o):(.u_boot_cmd+0x24): undefined reference to `do_irqinfo'
make: *** [u-boot] Error 1

imx27lite: Reenable MTD support on NOR flash.

2009-12-14T20:30:11+00:00

The support for this was silently dropped by a configuration
split during the merge of the imx27lite board support in commit
864aa034f3a0e10ce710e8bbda171df3cab59414 (cmd_mtdparts: Move to common
handling of FLASH devices via MTD layer).

nand: Fix access to last block in NAND devices

2009-12-11T19:11:57+00:00

Currently, the last block of NAND devices can't be accessed. This patch
fixes this issue by correcting the boundary checking (off-by-one error).

mpc83xx: boot time regression, move LCRR setup back to cpu_init_f

2009-12-09T17:40:52+00:00

Commit c7190f02 (retain POR values of non-configured ACR, SPCR, SCCR,
and LCRR bitfields) moved the LCRR assignment to after relocation
to RAM because of the potential problem with changing the local bus
clock while executing from flash.

This change unfortunately adversely affects the boot time, as running
all code up to cpu_init_r can cause significant slowdown.

E.G. on a 8347 board a bootup time increase of ~600ms has been observed:

   0.020 CPU:   e300c1, MPC8347_PBGA_EA, Rev: 3.0 at 400 MHz, CSB: 266.667 MHz
   0.168 RS:    232
   0.172 I2C:   ready
   0.176 DRAM:  64 MB
   1.236 FLASH: 32 MB

Versus:

   0.016 CPU:   e300c1, MPC8347_PBGA_EA, Rev: 3.0 at 400 MHz, CSB: 266.667 MHz
   0.092 RS:    232
   0.092 I2C:   ready
   0.096 DRAM:  64 MB
   0.644 FLASH: 32 MB

So far no boards have needed the late LCRR setup, so simply revert it
for now - If it is needed at a later time, those boards can either do
their own final LCRR setup in board code (E.G. in board_early_init_r),
or we can introduce a CONFIG_SYS_LCRR_LATE config option to only do
the setup in cpu_init_r.

microblaze: Correct ffs regression for Microblaze

We are using generic implementation of ffs. This should
be part of Simon's commit 0413cfecea350000eab5e591a0965c3e3ee0ff00

Here is warning message which this patch removes.

microblaze: Stop stack clobbering in microblaze-generic.

2009-12-08T07:51:42+00:00

A typo caused the stack and malloc regions to overlap, which prevented
mem_malloc_init() from returning. This commit makes the memory layout match
the example described in include/configs/microblaze-generic.h

MAKEALL: Fix return value

2009-12-07T22:06:42+00:00

Previously MAKEALL would always return a value of 0, even if 1 or more
boards did not compile.  This change causes MAKEALL to return 0 if all
boards were able to build, otherwise 1.

This change also requires changing the script interpreter from sh to
bash to support bash's PIPESTATUS variable.
