u-boot.git/arch/powerpc/include, branch v2011.12 Unnamed repository; edit this file 'description' to name the repository. mpc85xx: support for Freescale COM Express P2020 2011-11-29T15:07:51+00:00 Ira W. Snyder iws@ovro.caltech.edu 2011-11-23T16:25:58+00:00 9839709ea3df89f6021034508f48b97cab33ebb8 This adds support for the Freescale COM Express P2020 board. This board is similar to the P1_P2_RDB, but has some extra (as well as missing) peripherals. Unlike all other mpc85xx boards, it uses a watchdog timeout to reset. Using the HRESET_REQ register does not work. This board has no NOR flash, and can only be booted via SD or SPI. This procedure is documented in Freescale Document Number AN3659 "Booting from On-Chip ROM (eSDHC or eSPI)." Some alternative documentation is provided in Freescale Document Number P2020RM "P2020 QorIQ Integrated Processor Reference Manual" (section 4.5). Signed-off-by: Ira W.

powerpc/85xx: CONFIG_FSL_SATA_V2 should be defined in config_mpc85xx.h 2011-11-29T14:48:06+00:00 Timur Tabi timur@freescale.com 2011-11-21T23:10:22+00:00 3e0529f742e893653848494ffb9f7cd0d91304bf Macro CONFIG_FSL_SATA_V2 is defined if the SOC has a V2 Freescale SATA controller, so it should be defined in config_mpc85xx.h instead of the various board header files. So now CONFIG_FSL_SATA_V2 is always defined on the P1013, P1022, P2041, P3041, P5010, and P5020. It was already defined for the P1010 and P1014.

To ensure consistent timing results, Freescale recommends this feature be disabled in future customer products. There should be no impact to parts that are already operating in the field. Workaround: Prior to setting DDR_SDRAM_CFG[MEM_EN]=1, do the following: 1. Write a value of 0x0000_0015 to the register at offset CCSRBAR + DDR OFFSET + 0xf30 2. Write a value of 0x2400_0000 to the register at offset CCSRBAR + DDR OFFSET + 0xf54 Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org> 
Erratum A-003474: Internal DDR calibration circuit is not supported

Impact:
Experience shows no significant benefit to device operation with
auto-calibration enabled versus it disabled. To ensure consistent timing
results, Freescale recommends this feature be disabled in future customer
products. There should be no impact to parts that are already operating
in the field.

Workaround:
Prior to setting DDR_SDRAM_CFG[MEM_EN]=1, do the following:
1. Write a value of 0x0000_0015 to the register at offset
	CCSRBAR + DDR OFFSET + 0xf30
2. Write a value of 0x2400_0000 to the register at offset

Impact: Floating point arithmetic operations may result in an incorrect value. Workaround: Perform a read modify write to set bit 7 to a 1 in SPR 977 before executing any floating point arithmetic operation. This bit can be set when setting MSR[FP], and can be cleared when clearing MSR[FP]. Alternatively, the bit can be set once at boot time, and never cleared. There will be no performance degradation due to setting this bit. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
