2010-07-20powerpc/mpc85xx: Report FMAN # to match user manualEmil Medve
The user manual refers to FMAN1 and FMAN2 not 0 and 1. Signed-off-by: Emil Medve <Emilian.Medve@Freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2010-07-20powerpc/p4080: Add setting of clock-frequency for clockgen nodeKumar Gala
On QorIQ CoreNet based devices we have a global clocking block. We want to keep track of SYSCLK frequency as it is what is used to derive all other frequencies in the SoC Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2010-07-20powerpc/85xx: Use fdt_node_offset_by_compat_reg for clock-frequency updatesKumar Gala
Move to using fdt_node_offset_by_compat_reg to find the node offsets we want to update instead of using aliases. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2010-07-16powerpc/85xx: Move p1022ds slot code into board fileKumar Gala
The code to map SERDES configs to slot names is board specific and not chip specific. Thus it should live in board/freescale/p1022ds/ and not in arch/powerpc/cpu/. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2010-07-16powerpc/85xx: Add command to report errata workaroundsKumar Gala
Add 'errata' command to report what errata we workaround. Report workaround for erratum SATA-A001 on P1022/P1013. Also sorted the CONFIG_CMD_* list. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2010-07-16powerpc: add support for the Freescale P1022DS reference boardTimur Tabi
Specifics: 1) 36-bit only 2) Booting from NOR flash only 3) Environment stored in NOR flash only 4) No SPI support 5) No DIU support Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2010-07-16powerpc/85xx: Add recognition of e5500 coreKumar Gala

2010-07-16powerpc 83xx/85xx: Merge lbc upmconfig codeBecky Bruce
Each platform had its own version of the upmconfig, despite the init process being identical. Now that we have a spot for common lbc code, create a common upmconfig() there.

2010-07-16mpc85xx: Add reginfo commandBecky Bruce
The new command dumps the TLBCAM, the LAWs, and the BR/OR regs. Add CONFIG_CMD_REGINFO to the config for all MPC85xx parts. Signed-off-by: Becky Bruce <beckyb@kernel.crashing.org> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2010-07-16mpc85xx: Add print_tlbcam() functionBecky Bruce
This dumps out the contents of TLB1 on 85xx-based systems. Signed-off-by: Becky Bruce <beckyb@kernel.crashing.org> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
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.

2010-07-16powerpc/8xxx: Add is_core_disabled to remove disabled cores from dtbKumar Gala
If we explicitly disabled a core remove it from the dtb we pass on to the kernel. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
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
Add the ability to determine if a given IP block connected on SERDES is configured. This is useful for things like PCIe and SRIO since they are only ever connected on SERDES. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

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. CPU frequency is based on platform frequency in synchronous mode. Also fix: * Fixes the bit mask for DDR_SYNC (RCWSR5[184]) * Corrects the detection of synchronous mode.

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.
