2009-04-16at91sam9/at91cap: improve clock frameworkJean-Christophe PLAGNIOL-VILLARD
calculate dynamically the clock rate and pllb setting for usb Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
2009-04-06Blackfin: audit UART for all known anomaliesMike Frysinger
There is no code change here, just new comments, but this keeps me from having to do another audit from scratch in the future. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-04-06Blackfin: add check for anomaly 05000362Mike Frysinger
DESCRIPTION: The column address width settings for banks 2 and 3 are misconnected in the SDRAM controller. Accesses to bank 2 will result in an error if the Column Address Width for bank 3 (EB3CAW ) is not set to be the same as that of bank 2. WORKAROUND: If using bank 2, make sure that banks 2 and 3 have the same column address width settings in the EBIU_SDBCTL register. This must be the case regardless of whether or not bank 3 is enabled. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-04-06Blackfin: add workaround for anomaly 05000242Mike Frysinger
DESCRIPTION: If the DF bit is set prior to a hardware reset, the PLL will continue to divide CLKIN by 2 after the hardware reset, but the DF bit itself will be cleared in the PLL_CTL register. WORKAROUND: Reprogram the PLL with DF cleared if the desire is to not divide CLKIN by 2 after reset. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-04-06Blackfin: add workaround for anomaly 05000171Mike Frysinger
DESCRIPTION: The Boot ROM is executed at power up/reset and changes the value of the SICA_IWR registers from their default reset value of 0xFFFF, but does not restore them. WORKAROUND: User code should not rely on the default value of these registers. Set the desired values explicitly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-04-05mpc5200: reduce delays in i2cJon Smirl
The previous code waited 1000us before checking i2c status. Measurement shows i2c is usually ready in under 50us. Change the polling interval to 15us, loop 6,667 times to keep the polling timeout constant at 100ms.
2009-04-05OMAP: Fix compile issueSanjeev Premi
Fixes this compile error: board.c: In function 'do_switch_ecc': board.c:339: error: 'cmd_tbl_t' has no member named 'help' make[1]: *** [board.o] Error 1 make[1]: Leaving directory `/db/psp_git/users/a0756819/u-boot/cpu/arm_cortexa8/omap3' make: *** [cpu/arm_cortexa8/omap3/libomap3.a] Error 2 This is due to the fact that current command uses long help for the usage print even if the CONFIG_SYS_LONGHELP is not enabled.

2009-04-05Move machine specific code to board at s3c64xx (v2)Kyungmin Park
Move machine specific code to smdk6400. Some board use OneNAND instead of NAND. Some register MP0_CS_CFG[5:0] are controled by both h/w and s/w. So it's better to use macro instead of hard-coded value. Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>

2009-04-02Blackfin: fix crash when booting from external memoryMike Frysinger
When testing a u-boot binary that hasn't been booted from the bootrom, we have to make sure the bootstruct structure has sane storage space. If we don't, the initcode will crash when it tries to dereference an invalid pointer. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-04-0185xx: Introduce determine_mp_bootpg() helper.Kumar Gala
Match determine_mp_bootpg() that was added for 86xx. We need this to address a bug introduced in v2009.03 with 86xx MP booting. We have to make sure to reserve the region of memory used for the MP bootpg() so other u-boot code doesn't use it. Also added a comment about how cpu_reset() is dealing w/an errata on early 85xx MP HW. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-04-0186xx: Cleanup MP supportKumar Gala
* Use CONFIG_MP instead of CONFIG_NUM_CPUS to match 85xx * Introduce determine_mp_bootpg() helper. We'll need this to address a bug introduced in v2009.03 with 86xx MP booting. We have to make sure to reserve the region of memory used for the MP bootpg() so other u-boot code doesn't use it. * Added dummy versions of cpu_reset(), cpu_status() & cpu_release() to allow cmd_mp.c to build and work. In the future we should look at implementing all these functions. This could be common w/85xx if we use spin tables on 86xx. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-03-30MPC85xx: Add MPC8569 CPU supportHaiying Wang
There is a workaround for MPC8569 CPU Errata, which needs to set Bit 13 of LBCR in 4K bootpage. We setup a temp TLB for eLBC controller in bootpage, then invalidate it after LBCR bit 13 is set.

2009-03-30fsl-ddr: Fix two bugs in the ddr infrastructureDave Liu
1. wr_lat UM said the total write latency for DDR2 is equal to WR_LAT + ADD_LAT, the write latency is CL + ADD_LAT - 1. so, the WR_LAT = CL - 1; 2. rd_to_pre we missed to add the ADD_LAT for DDR2 case.
