* PPC: Record U-Boot's relocated address in RAM and show in bdinfo.Richard Retanubun2010-03-11-2/+0
| | | | | | | | | | | This patch uses gd->relocaddr variable to store uboot's relocated address in RAM and shows it in bdinfo command. This patch moves CONFIG_AMIGAONEG3SE style copying of the address in board_init_f to just before relocation is actually done.

* ppc/85xx: Add tracking of TLB CAM usageKumar Gala2010-01-05-0/+12
| | | | | | | | | We need to track which TLB CAM entries are used to allow us to "dynamically" allocate entries later in the code.

* 85xx: MP Boot Page Translation updatePeter Tyser2009-10-27-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change has 3 goals: - Have secondary cores be released into spin loops at their 'true' address in SDRAM. Previously, secondary cores were put into spin loops in the 0xfffffxxx address range which required that boot page translation was always enabled while cores were in their spin loops. - Allow the TLB window that the primary core uses to access the secondary cores boot page to be placed at any address. Previously, a TLB window at 0xfffff000 was always used to access the seconary cores' boot page. This TLB address requirement overlapped with other peripherals on some boards (eg XPedite5370). By default, the boot page TLB will still use the 0xfffffxxx address range, but this can be overridden on a board-by-board basis by defining a custom CONFIG_BPTR_VIRT_ADDR. Note that the TLB used to map the boot page remains in use while U-Boot executes. Previously it was only temporarily used, then restored to its initial value. - Allow Boot Page Translation to be disabled on bootup. Previously, Boot Page Translation was always left enabled after secondary cores were brought out of reset. This caused the 0xfffffxxx address range to somewhat "magically" be translated to an address in SDRAM. Some boards may not want this oddity in their memory map, so defining CONFIG_MPC8xxx_DISABLE_BPTR will turn off Boot Page Translation after the secondary cores are initialized. These changes are only applicable to 85xx boards with CONFIG_MP defined. Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | | Commit 054197ba and later fixes used an array to initialize some of the MDDRC parameters; however, the use of an array turned out to be a bad idea as it was not possible to correlate structure entries to array indices in readable and reliable way. Now we use a struct instead, which makes this self-explanatory. Signed-off-by: Wolfgang Denk <wd@denx.de>

* | ppc4xx: Merge PPC4xx DDR and DDR2 ECC handlingStefan Roese2009-10-02-3/+4
|/ | | | | | | | | | | | | | | | | This patch merges the ECC handling (ECC parity byte writing) into one file (ecc.c) for all PPC4xx SDRAM controllers except for PPC440EPx/GRx. This exception is because only those PPC's use the completely different Denali SDRAM controller core. Previously we had two routines to generate/write the ECC parity bytes. With this patch we now only have one core function left. Tested on Kilauea (no ECC) and Katmai (with and without ECC).

| | | | | | | | | | | | | | | | On CoreNet based platforms the LAW address is split between an high & low register and we no longer shift the address. Also, the target IDs on CoreNet platforms have been completely re-assigned. Additionally, added a new find_law() API to which LAW an address hits in. This is need for the CoreNet style boot release code since it will need to determine what the target ID should be set to for boot window translation. Finally, enamed LAWAR_EN to LAW_EN and moved to header so we can use it elsewhere. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* ppc/p4080: Add p4080 platform immap definitionsKumar Gala2009-09-24-20/+271
| | | | | | | | | | | | | | | The p4080 SoC has a significant amount of commonality with the 85xx/PQ3 platform. We reuse the 85xx immap and just add new definitions for local access and global utils. The global utils is now broken into global utils, clocking and run control/power management. The offsets from CCSR for a number of blocks have also changed. We introduce the CONFIG_FSL_CORENET define to distinquish the PQ3 style of platform from the new p4080 platform. We don't use QoirQ as there are products (like p2020) that are PQ3 based platforms but have the QoirQ name. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
