This is needed in unlock_ram_in_cache() because it is called from C and
will corrupt the small data area anchor that is kept in R2.
lock_ram_in_cache() is modified similarly as good coding practice, but
is not called from C.

For some reason we duplicated the majority of code in lib_ppc/interrupts.c
Not know how that happened, but there is no good reason for it.
Use the interrupt_init_cpu() and timer_interrupt_cpu() since its why
they exist.

Measurements with our MPC8544 board showed that the I2C bus frequency
is wrong by a factor of 1.5. Obviously, the interpretation of the
MPC85xx_PORDEVSR2_SEC_CFG bit of the cfg_sec_freq register is not
correct. There seems to be an error in the 8544 RM.

get_cpu_board_revision() returned board revision based on information stored
in global static struct eeprom. It should instead use one from local struct
board_eeprom, to which the data is actually read from EEPROM. The bug led to
system hang after printing L1 cache information on U-Boot startup. The problem
was observed on MPC8555CDS system and possibly affects other Freescale MPC85xx
boards using CFG_I2C_EEPROM_CCID.
The change has been successfully tested on MPC8555CDS system.

Kumar has already added alias expansion to fdt_path_offset().
However, in some circumstances it may be convenient for the user of

fdt_path_offset().

The CFI flash driver starts at flash_init() which calls down into
flash_get_size(). This starts by calling flash_detect_cfi(). If said
function fails, flash_get_size() finishes by attempting to reset the
flash. Unfortunately, it does this with an info->portwidth set to 0x10
which filters down into flash_make_cmd() and that happily smashes the
stack by sticking info->portwidth bytes into a cfiword_t variable that
lives on the stack. On a 64bit system you probably won't notice, but
killing the last 8 bytes on a 32bit system usually leads to a corrupt
return address. Which is what happens on a Blackfin system.

The current implementation of fdt_get_path() has a couple of bugs,
fixed by this patch.
First, contrary to its documentation, on success it returns the length
of the node's path, rather than 0. The testcase is correspondingly
wrong, and the patch fixes this as well.
Second, in some circumstances, it will return -FDT_ERR_BADOFFSET
instead of -FDT_ERR_NOSPACE when given insufficient buffer space.
Specifically this happens when there is insufficient space even to
hold the path's second last component. This behaviour is corrected,
and the testcase updated to check it.
