* powerpc/85xx & 86xx: Rework ft_fsl_pci_setup to not require aliasesKumar Gala2010-07-20-116/+22
| | | | | | | | | | | Previously we used an alias the pci node to determine which node to fixup or delete. Now we use the new fdt_node_offset_by_compat_reg to find the node to update. Additionally, we replace the code in each board with a single macro call that makes assumes uniform naming and reduces duplication in this area. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* powerpc/86xx: Rename PCI1/2 to PCIE1/2 on MPC8641HPCN & SBC8641Kumar Gala2010-07-20-38/+38
| | | | | | | | The MPC8641 boards actually only have PCIE not PCI. Rename so we are uniform with regards to names so we can replace this code with templated code. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* powerpc/86xx: Move PCI/PCIe address defines into common immap_86xx.hKumar Gala2010-07-20-2/+2
| | | | | | | | Remove dupliacted setting of PCI/PCIe address and offsets in board config.h. Renamed CONFIG_SYS_PCI1/2_ADDR to CONFIG_SYS_PCI1/2ADDR on MPC8641 boards since its really PCIE controllers and not PCI. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* 83xx/85xx/86xx: LBC register cleanupBecky Bruce2010-07-16-55/+37
| | | | | | | | | | | | | | | | | | | | | 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.

* ppc/85xx: Add a structure defn for PIXIS registersKumar Gala2010-07-16-1/+183
| | | | | | | | | | | | | The various boards that have PIXIS FPGAs have slightly different register definitions, however there is some common functionality (like reset, ICS307 clk control, etc) that can be shared. The struct definition exists for MPC8536DS, MPC8544DS, MPC8572DS, MPC8610HPCD, and MPC8641HPCN boards. Also fixed ngpixis to be __packed__ instead of aligned.

* MPC8308RDB: minimal support for devboard from FreescaleIlya Yanok2010-07-09-0/+339
| | | | | | | | | | | | | | | | | | | | | This patch provides support for MPC8308RDB development board from Freescale with a minimal set of features: Dual UART is supported NOR flash is supported Both TSEC Ethernet controllers are supported PCI Express initialization is supported The following features are enabled in configuration but not fully tested: I2C (used to get the board revision) I2C-connected RTC VSC7385 switch There is one (hopefully) minor issue: on soft reset the board sometimes resets twice. I've not managed to find the fix for this problem yet. As a workaround instruction cache can be disabled.

* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) { ...

| | | | | | | | | | | | | | | | | | | | | | | | 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.

* p2020ds: add alternate boot bank support using the ngPIXIS FPGATimur Tabi2010-04-07-35/+214
| | | | | | | | | | | | | | | The Freescale P2020DS board uses a new type of PIXIS FPGA, called the ngPIXIS. The ngPIXIS has one distinct new feature: the values of the on-board switches can be selectively overridden with shadow registers. This feature is used to boot from a different NOR flash bank, instead of having a register dedicated for this purpose. Because the ngPIXIS is so different from the previous PIXIS, a new file is introduced: ngpixis.c. Also update the P2020DS checkboard() function to use the new macros defined in the header file.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Refactor and document the Freescale PIXIS code, used on most 85xx and 86xx boards. This makes the code easier to read and more flexible. Delete pixis.h, because none of the exported functions were actually being used by any other file. Make all of the functions in pixis.c 'static'. Remove "#include pixis.h" from every file that has it. Remove some unnecessary #includes. Make 'pixis_base' into a macro, so that we don't need to define it in every function. Add "while(1);" loops at the end of functions that reset the board, so that execution doesn't continue while the reset is in progress. Replace in_8/out_8 calls with clrbits_8, setbits_8, or clrsetbits_8, where appropriate. Replace ulong/uint with their spelled-out equivalents. Remove unnecessary typecasts, changing the types of some variables if necessary. Add CONFIG_SYS_PIXIS_VCFGEN0_ENABLE and CONFIG_SYS_PIXIS_VBOOT_ENABLE to make it easier for specific boards to support variations in the PIXIS registers sets. No current boards appears to need this feature. Fix the definition of CONFIG_SYS_PIXIS_VBOOT_MASK for the MPC8610 HPCD. Apparently, "pixis_reset altbank" has never worked on this board.

|/ | | | | | | | | | | | | | | | | | | | After determining how much DDR is actually in the system, set DBAT0 and IBAT0 accordingly. This ensures that the CPU won't attempt to access (via speculation) addresses outside of actual memory. On 86xx systems, DBAT0 and IBAT0 (the BATs for DDR) are initialized to 2GB and kept that way. If the system has less than 2GB of memory (typical for an MPC8610 HPCD), the CPU may attempt to access this memory during speculation. The zlib code is notorious for generating such memory reads, and indeed on the MPC8610, uncompressing the Linux kernel causes a machine check (without this patch). Currently we are limited to power of two sized DDR since we only use a single bat. If a non-power of two size is used that is less than CONFIG_MAX_MEM_MAPPED u-boot will crash.
