2010-11-11powerpc/85xx: rename CONFIG_SYS_TEXT_BASE to CONFIG_SYS_MONITOR_BASEHaiying Wang
Use CONFIG_SYS_MONITOR_BASE instead of CONFIG_SYS_TEXT_BASE in early init code so we can share the same code with NAND or NOR boot and not have additional ifdefs in here. Signed-off-by: Haiying Wang <Haiying.Wang@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2010-10-29Replace CONFIG_RELOC_FIXUP_WORKS by CONFIG_NEEDS_MANUAL_RELOCWolfgang Denk
By now, the majority of architectures have working relocation support, so the few remaining architectures have become exceptions. To make this more obvious, we make working relocation now the default case, and flag the remaining cases with CONFIG_NEEDS_MANUAL_RELOC.

2010-10-26Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated valueWolfgang Denk
CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not being able to use "sizeof(struct global_data)" in assembler files. Recent experience has shown that manual synchronization is not reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into GENERATED_GBL_DATA_SIZE which gets automatically generated by the asm-offsets tool. In the result, all definitions of this value can be deleted from the board config files. We have to make sure that all files that reference such data include the new <asm-offsets.h> file. No other changes have been done yet, but it is obvious that similar changes / simplifications can be done for other, related macro definitions as well.

2010-10-26Rename CONFIG_SYS_INIT_RAM_END into CONFIG_SYS_INIT_RAM_SIZEWolfgang Denk
CONFIG_SYS_INIT_RAM_END was a misnomer as it suggests this might be some end address; to make the meaning more clear we rename it into CONFIG_SYS_INIT_RAM_SIZE No other code changes are performed in this patch, only minor editing of white space (due to the changed length) and the comments was done, where noticed. Note that the code for the PATI and cmi_mpc5xx board configurations looks seriously broken.

2010-10-2085xx: Add support for not releasing secondary cores via 'mp_holdoff'Aaron Sierra
Some OSes require that secondary cores not be initialized when they are booted (eg VxWorks). By default when U-Boot is compiled with the CONFIG_MP option all secondary cores are brought out of reset and held in spinloops. Setting the "mp_holdoff" environment variable to 'yes' or '1' will cause U-Boot to leave secondary cores in their default state.

2010-10-20Add memory test feature for mpc85xx POST.York Sun
The memory test is performed after DDR initialization when U-boot stills runs in flash and cache. On recent mpc85xx platforms, the total memory can be more than 2GB. To cover whole memory, it needs be mapped 2GB at a time using a sliding TLB window. After the testing, DDR is remapped with up to 2GB memory from the lowest address as normal. If memory test fails, DDR DIMM SPD and DDR controller registers are dumped for further debugging. Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2010-10-07powerpc/85xx: fix rev.2 job queue LIODN error stormKim Phillips
pumping line-rate traffic though a p4080 rev.2, which is configured to encrypt packets prior to forwarding through an IPsec tunnel, gets this error: of_platform ffe302000.jq: DECO: desc idx 22: LIODN error. DECO was trying to share from itself or from another DECO but the two Non-SEQ LIODN values didn't match or the "shared from" DECO's Descriptor required that the SEQ LIODNs be the same and they aren't. Since high traffic rates cause DECOs to begin to start sharing shared descriptors amongst themselves, and DECOs inherit job queue LIODNs when accessing shared descriptors, and a recently discovered rev.2 h/w erratum requires all sharing job queues in a partition have same liodn assignment, reassign the first job queue's liodn assignment to the rest.

2010-09-23ppc4xx: Cleanup of PVR detection code in cpu.cStefan Roese
This patch cleans the PVR detection code in check_cpu() up a bit. Basically the strings are better seperated, resulting in an easier to understand and maintain code version. The #ifdef's couldn't be removed easily because of two reasons: - Some SoC revisions have the same PVR, so need a way to differentiate between those two SoC's. - In some case statements registers only available in this SoC variant are referenced. Instead I moved the CONFIG_440 #ifdef a bit, so that 405 platforms don't add this 440 detection code and vice versa. Resulting in this U-Boot image size change: 405EX (Kilauea): 408 bytes less 440EPx (Sequoia): 604 bytes less 460EX (Canyonlands): 564 bytes less Signed-off-by: Stefan Roese <sr@denx.de> Cc: Wolfgang Denk <wd@denx.de>

This patch removes the PPC4xx UART driver. Instead the common NS16550 driver is used, since all PPC4xx SoC's use this peripheral device. The file 4xx_uart.c now only implements the UART clock calculation function which also sets the SoC internal UART divisors.

2010-09-23ppc4xx: Big header cleanup part 2, mostly PPC405 relatedStefan Roese
This cleanup is done by creating header files for all SoC versions and moving the SoC specific defines into these special headers. This way the common header ppc405.h and ppc440.h can be cleaned up finally. As a part from this cleanup, the GPIO definitions for PPC405EP are corrected. The high and low parts of the registers (for example CONFIG_SYS_GPIO0_OSRL vs. CONFIG_SYS_GPIO0_OSRH) have been defined in the wrong order. This patch now fixes this issue by switching these xxxH and xxxL values. This brings the GPIO 405EP port in sync with all other PPC4xx ports. Signed-off-by: Stefan Roese <sr@denx.de>
