2011-04-04powerpc/8xxx: Refactor fsl_ddr_get_spd into common code from boardKumar Gala
Move fsl_ddr_get_spd into common mpc8xxx/ddr/main.c as most boards pretty much do the same thing. The only variations are in how many controllers or DIMMs per controller exist. To make this work we standardize on the names of the SPD_EEPROM_ADDRESS defines based on the use case of the board. We allow boards to override get_spd to either do board specific fixups to the SPD data or deal with any unique behavior of how the SPD eeproms are wired up.

2011-04-04powerpc/8xxx: Replace fsl_ddr_get_mem_data_rate with get_ddr_freq()Kumar Gala
Every 85xx board implements fsl_ddr_get_mem_data_rate via get_ddr_freq() and every 86xx board uses get_bus_freq(). If implement get_ddr_freq() as a static inline to call get_bus_freq() we can remove fsl_ddr_get_mem_data_rate altogether and just call get_ddr_freq() directly.

2011-04-04powerpc: Move cpu specific lmb reserve to arch_lmb_reserveKumar Gala
We've been utilizing board_lmb_reserve to reserve the boot page for MP systems. We can just move this into arch_lmb_reserve for 85xx & 86xx systems rather than duplicating in each board port. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2011-03-22Introduce a new linker flag LDFLAGS_FINALHaiying Wang
commit 8aba9dceebb14144e07d19593111ee3a999c37fc Divides variable of linker flags to LDFLAGS-u-boot and LDFLAGS breaks the usage of --gc-section to build nand_spl. We still need linker option --gc-section for every uboot image, not only the main one. LDFLAGS_FINAL passes the --gc-sections to each uboot image. To get the proper linker flags, we use LDFLAGS and LDFLAGS_FINAL to replace PLATFORM_LDFLAGS in the Makefile of each nand_spl board.

2011-03-15powerpc/85xx: Fix synchronization of timebase on MP bootKumar Gala
There is a small ordering issue in the master core in that we need to make sure the disabling of the timebase in the SoC is visible before we set the value to 0.

2011-03-13mpc8[5/6]xx: Ensure POST word does not get resetJohn Schmoller
The POST word is stored in a spare register in the PIC on MPC8[5/6]xx processors. When interrupt_init() is called, this register gets reset which resulted in all POST_RAM POSTs not being ran due to the corrupted POST word. To resolve this, store off POST word before the PIC is reset, and restore it after the PIC has been initialized.

2011-02-21ARM: fix write*() I/O accessorsWolfgang Denk
Commit 3c0659b "ARM: Avoid compiler optimization for readb, writeb and friends." introduced I/O accessors with memory barriers. Unfortunately the new write*() accessors introduced a bug: The problem is that the argument "v" gets evaluated twice. This breaks code like used here (from "drivers/net/dnet.c"): for (i = 0; i < wrsz; i++) writel(*bufp++, &dnet->regs->TX_DATA_FIFO); Use auxiliary variables to avoid such problems.
