* ppc4xx: PPC44x MQ initializationStefan Roese2008-10-17-4/+6
| | | | | | | | | | | | | | | | | | | Set the MQ Read Passing & MCIF Cycle limits to the recommended by AMCC values. This fixes the occasional 440SPe hard locking issues when the 440SPe's dedicated DMA engines are used (e.g. by the h/w accelerated RAID driver). Previously the appropriate initialization had been made in Linux, by the ppc440spe ADMA driver, which is wrong because modifying the MQ configuration registers after normal operation has begun is not supported and could have unpredictable results. Comment from Stefan: This patch doesn't change the resulting value of the MQ registers. It explicitly sets/clears all bits to the desired state which better documents the resulting register value instead of relying on pre-set default values.

| * ARM DaVinci: Fix broken HW ECC for large page NAND.Hugo Villeneuve2008-09-10-5/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on original patch by Bernard Blackham <bernard@largestprime.net> U-boot's HW ECC support for large page NAND on Davinci is completely broken. Some kernels, such as the 2.6.10 one supported by MontaVista for DaVinci, rely upon this broken behaviour as they share the same code for ECCs. In the existing scheme, error detection *might* work on large page, but error correction definitely does not. Small page ECC correction works, but the format is not compatible with the mainline git kernel. This patch adds ECC code that matches what is currently in the Davinci git repository (since NAND support was added in 2.6.24). This makes the ECC and OOB layout written by u-boot compatible with Linux for both small page and large page devices and fixes ECC correction for large page devices. The old behaviour can be restored by defining the macro CFG_DAVINCI_BROKEN_ECC, which is undefined by default.

Two alternate SDRAM DDR autocalibration algoritm are provided in this patch, "Method_A" and "Method_B". DDR autocalibration Method_A scans the full range of possible PPC4xx SDRAM Controller DDR autocalibration values and takes a lot longer to run than Method_B. Method_B executes in the same amount of time as the currently existing DDR autocalibration routine, i.e. 1 second or so. Normally Method_B is used and it is set as the default method. The current U-Boot PPC4xx DDR autocalibration code calibrates the IBM SDRAM Controller registers.[bit-field]: 1) SDRAM0_RQDC.[RQFD] 2) SDRAM0_RFDC.[RFFD] This alternate PPC4xx DDR autocalibration code calibrates the following IBM SDRAM Controller registers.[bit-field]: 1) SDRAM0_WRDTR.[WDTR] 2) SDRAM0_CLKTR.[CKTR] 3) SDRAM0_RQDC.[RQFD] 4) SDRAM0_RFDC.[RFFD] and will also use the calibrated settings of the above four registers that produce the best "Read Sample Cycle Select" value in the SDRAM0_RDCC.[RDSS] register.[bit-field].

The Arbiter Event Register can record the type and effective address of an arbiter error, even through an HRESET. This patch stores the values in the global data structure. Display of the Arbiter Event registers immediately after the RSR value can be enabled with defines. The Arbiter values will only be displayed if an arbiter event has occured since the last Power On Reset, and either of the following defines exist: #define CONFIG_DISPLAY_AER_BRIEF - display only the arbiter address and and type register values #define CONFIG_DISPLAY_AER_FULL - display and interpret the arbiter event register values Address Only transactions are one of the trapped events that can register as an arbiter event. They occur with some cache manipulation instructions if the HID0_ABE (Address Broadcast Enable) is set and the memory region has the MEMORY_COHERENCE WIMG bit set. Setting: #define CONFIG_MASK_AER_AO - prevents the arbiter from recording address only events, so that it can still capture other real problems.
