11 years agofdt: Fix bug in size calculation in fdt_resize() with initrd use
Feng Wang [Tue, 3 Aug 2010 14:22:43 +0000 (16:22 +0200)]
fdt: Fix bug in size calculation in fdt_resize() with initrd use

Original bug description from Feng (fdt_resize() bug caused "WARNING:
could not set linux, initrd-start FDT_ERR_NOSPACE."):

What I got is an error: "WARNING: could not set linux,initrd-start
FDT_ERR_NOSPACE." after loading Device Tree blob. This in turn caused
linux to miss init part.

After some digging, I found out the reason for this error, it is caused
by fdt_resize().

FDT blob got resized after filling in all board specific information of
PowerPC. (in boot_body_linux()). It reduced blob size with only extra
space for two fdt_reserve_entry, one for fdt itself, and one for initrd.
Then it's aligned to a 0x1000 page boundary. However, later in
fdt_initrd(), it could add two more properties, initrd-start AND
initrd-end, each one needs at least two fdt_reserve_entry sizes done by
_fdt_add_property() (name and value). Thus, the two fdt_reserve_entry
extra space is not sufficient.

So for some specific fdt size which is just under the page boundary
after resizing, this will cause an error of FDT_ERR_NOSPACE in
fdt_initrd() when setting those two properties, and failed to pass
initrd information to linux.

My fix is in fdt_resize(), leave at least 4 fdt_reserve_entry for
initrd. So instead of 2*sizeof(struct fdt_reserve_entry) for
actual_totalsize, use 5*sizeof(struc fdt_reserve_entry).

Stefan: I got this same error on katmai, when trying to boot with
initrd (run flash_self). This patch fixes this issue.

ppc4xx: T3CORP fixes and updates

This patch fixes some problems for the T3CORP board. Here the list
of the changes:

- Add 600-67 and 677 CPU frequency setting to chip_config
  command
- Define CONFIG_DDR_RFDC_FIXED on t3corp:
  While using the "normal" auto calibration code, sometimes values for
  RFDC were picked (>= T3) that resulted in a non-working U-Boot (hang
  upon relocation, while running from SDRAM). With this optimized RFDC
  value we can force this register and use the auto-calibration code to
  setup the remaining calibration registers.
- Increase sizes of FPGA chips selects
- EBC timing updated OEN=3 for 66 MHz EBC speed
- Change ext. IRQ2 setup to level-low active
- Enable CONFIG_SYS_CFI_FLASH_STATUS_POLL

By defining CONFIG_SYS_CFI_FLASH_STATUS_POLL, DQ7 is polled to detect the
chip busy status. This is now used instead of the data toggle method which
is used historically by default in the common CFI driver. With this change
a problem with not written data is solved on this board, where a 32 byte
block of data is still erased instead of filled with the correct content
