* 85xx: Fix how we map DDR memoryKumar Gala2009-02-16-1/+3
| | | | | | | | | Previously we only allowed power-of-two memory sizes and didnt handle >2G of memory. Now we will map up to CONFIG_MAX_MEM_MAPPED and should properly handle any size that we can make in the TLBs we have available to us Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* ppc4xx: Autocalibration can set RDCC to over aggressive value.Adam Graham2009-02-12-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The criteria of the AMCC SDRAM Controller DDR autocalibration U-Boot code is to pick the largest passing write/read/compare window that also has the smallest SDRAM_RDCC.[RDSS] Read Sample Cycle Select value. On some Kilauea boards the DDR autocalibration algorithm can find a large passing write/read/compare window with a small SDRAM_RDCC.[RDSS] aggressive value of Read Sample Cycle Select value "T1 Sample". This SDRAM_RDCC.[RDSS] Read Sample Cycle Select value of "T1 Sample" proves to be to aggressive when later on U-Boot relocates into DDR memory and executes. The memory traces on the Kilauea board are short so on some Kilauea boards the SDRAM_RDCC.[RDSS] Read Sample Cycle Select value of "T1 Sample" shows up as a potentially valid value for the DDR autocalibratiion algorithm. The fix is to define a weak default function which provides the minimum SDRAM_RDCC.[RDSS] Read Sample Cycle Select value to accept for DDR autocalibration. The default will be the "T2 Sample" value. A board developer who has a well defined board and chooses to be more aggressive can always provide their own board specific string function with the more aggressive "T1 Sample" value or stick with the default minimum SDRAM_RDCC.[RDSS] value of "T2". Also put in a autocalibration loop fix for case where current write/read/compare passing window size is the same as a prior window size, then in this case choose the write/read/compare result that has the associated smallest RDCC T-Sample value.

* ppc4xx: Fix problem with CONFIG_MAX_MEM_MAPPED in include/asm-ppc/config.hStefan Roese2009-02-12-2/+2
| | | | | | | | | | CONFIG_SDRAM_PPC4xx_IBM_DDR2 is not set when include/asm-ppc/config.h is included. So for katmai, CONFIG_MAX_MEM_MAPPED will get set to 256MB. It makes perfect sense to set CONFIG_MAX_MEM_MAPPED to 2GB for all PPC4xx boards right now. Signed-off-by: Stefan Roese <sr@denx.de>

Also, remove the BL_xxx defines that were only used by the alaska board, and switch to using the BATU_BL_xxx defines used by all the other boards. The BL_ defines previously in use had to be shifted into the proper position for use, which was inefficient. Signed-off-by: Becky Bruce <beckyb@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | | | | | | The eLBC only handles 32-bit physical address in systems with 36-bit physical. The previos generation of LBC handled 34-bit physical address in 36-bit systems. Added a new CONFIG option to convey the difference between the LBC and eLBC.

| | | | | | | | | | | | | | | | | | | | | | | | | | Some 85xx processors have the advanced power management feature, such as wake up ARP, that needs enable the automatic self refresh.

| * | mpc83xx: Add support for MPC83xx PCI-E controllersAnton Vorontsov2009-01-21-7/+114
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for MPC83xx PCI-E controllers in Root Complex mode. The patch is based on Tony Li and Dave Liu work[1]. Though unlike the original patch, by default we don't register PCI-E buses for use in U-Boot, we only configure the controllers for future use in other OSes (Linux). This is done because we don't have enough of spare BATs to map all the PCI-E regions. To actually use PCI-E in U-Boot, users should explicitly define CONFIG_83XX_GENERIC_PCIE_REGISTER_HOSES symbol in the board file. And only then U-Boot will able to access PCI-E, but at the cost of disabled address translation.

* mpc8[56]xx: Put localbus clock in sysinfo and gdTrent Piepho2008-12-19-0/+3
| | | | | | | | | | | | | | | | | | | | | | | Currently MPC85xx and MPC86xx boards just calculate the localbus frequency and print it out, but don't save it. This changes where its calculated and stored to be more consistent with the CPU, CCB, TB, and DDR frequencies and the MPC83xx localbus clock. The localbus frequency is added to sysinfo and calculated when sysinfo is set up, in cpu/mpc8[56]xx/speed.c, the same as the other frequencies are. get_clocks() copies the frequency into the global data, as the other frequencies are, into a new field that is only enabled for MPC85xx and MPC86xx. checkcpu() in cpu/mpc8[56]xx/cpu.c will print out the local bus frequency from sysinfo, like the other frequencies, instead of calculating it on the spot.

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.

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.
