2010-08-19mpx85xx/fdt: Add cpu-release-addr for all coresMatthew McClintock
We currently do not add a cpu-release-addr for core 0, this is needed when we want to reset core 0 and later restart it from Linux Signed-off-by: Matthew McClintock <msm@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2010-07-26powerpc/p4080: Add support for initializing SERDESKumar Gala
Add support for initializing the SERDES blocks on CoreNet style QoriQ devices and the p4080 specific SERDES tables to know which actual componetns are enabled. Additionally, split out the Frame Manger (FMAN) into its specific ethernet ports instead of gross level of the full FMAN.

If 36-bit physical address is used, move the INIT_RAM_ADDR to higher address. This frees the low 4GB address space for better use. Signed-off-by: York Sun <yorksun@freescale.com>
2010-07-21powerpc/85xx: Rework P1022 SERDES is_serdes_configured supportKumar Gala
Move serdes init until after we are in ram so we can keep track of a global static protocal map for the particular serdes config we are in. This makes is_serdes_configured() much simplier and not constantly reading registers to determine if a given device is enabled based on the protocol.

2010-07-16mpc85xx: tlb.c cleanupsBecky Bruce
Extract the operation to read a tlb into a function - we will need this later to print out the tlbs, and there's no point in duplicating the code. Create a TSIZE_TO_BYTES macro to deal with the conversion from the MAS field to an actual size instead of duplicating this in code. There are a few misc other minor cleanups.

2010-07-1683xx/85xx/86xx: LBC register cleanupBecky Bruce
Currently, 83xx, 86xx, and 85xx have a lot of duplicated code dedicated to defining and manipulating the LBC registers. Merge this into a single spot. To do this, we have to decide on a common name for the data structure that holds the lbc registers - it will now be known as fsl_lbc_t, and we adopt a common name for the immap layouts that include the lbc - this was previously known as either im_lbc or lbus; use the former. In addition, create accessors for the BR/OR regs that use in/out_be32 and use those instead of the mismash of access methods currently in play. I have done a successful ppc build all and tested a board or two from each processor family.

2010-07-04Make sure that argv[] argument pointers are not modified.Wolfgang Denk
The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make 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; while (*++arg) { switch (*arg) { ...

2010-05-1285xx/fsl-sata: Use is_serdes_configured() to determine if SATA is enabledKumar Gala
On the MPC85xx platform if we have SATA its connected on SERDES. Determing if SATA is enabled via sata_initialize should not be board specific and thus we move it out of the MPC8536DS board code. Additionally, now that we have is_serdes_configured() we can determine if the given SATA port is enabled and error out if its not in the driver. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2010-05-1285xx: Add is_serdes_configured() support to MPC8536 SERDESKumar Gala

2010-04-26ppc/p4080: Fix synchronous frequency calculationsSrikanth Srinivasan
When DDR is in synchronous mode, the existing code assigns sysclk frequency to DDR frequency. It should be synchronous with the platform frequency.

2010-04-21Move arch/ppc to arch/powerpcStefan Roese
As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.
