* ppc4xx: katmai: Change default configYuri Tikhonov2008-11-21-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables support for EXT2, and increases the CONFIG_SYS_BOOTMAPSZ size for the default configuration of the katmai boards to use them as the RAID-reference AMCC setups. EXT2 enabling allows one to boot kernels from the EXT2 formatted Compact Flash cards. CONFIG_SYS_BOOTMAPSZ increasing allows one to boot the Linux kernels, which use PAGE_SIZE of 256KB. Otherwise, the memory area with DTB file (which is placed at the end of the bootmap area) will turn out to be overlapped with the BSS segment of the 256KB kernel, and zeroed in early_init() of Linux. Actually, increasing of the bootmap size could be done via setting of the bootm_size U-Boot variable, but it looks like the current U-Boot implementation have some bootm_size- related functionality lost. In many places through the U-Boot code the CONFIG_SYS_BOOTMAPSZ definition is used directly (instead of trying to read the corresponding value from the environment). The same is truth for the boot_jump_linux() function in lib_ppc/bootm.c, where U-Boot transfers control to Linux passing the CONFIG_SYS_BOOTMAPSZ (not bootm_size) value to the booting kernel.

* ppc4xx: Changed 460EX/GT OCM TLB and internal SRAM initializationDave Mitchell2008-11-21-9/+22
| | | | | | | | | | | | | | | | | | Expanded OCM TLB to allow access to 64K OCM as well as 256K of internal SRAM. Adjusted internal SRAM initialization to match updated user manual recommendation. OCM & ISRAM are now mapped as follows: physical virtual size ISRAM 0x4_0000_0000 0xE300_0000 256k OCM 0x4_0004_0000 0xE304_0000 64k A single TLB was used for this mapping.

* ppc4xx: Delete unused definitions for SDR0_DDRCFG from ppc4xx.hSteven A. Falco2008-11-21-12/+3
| | | | | | | | | | | | | The definitions of bits in SDR_CFG are incorrect, and not used within U-Boot. Therefore, they can be removed. The naming of the sdr_ddrdl/sdr_cfg registers do not follow conventions, and are unused, so they can be removed too. A definition for SDR0_DDRCFG is added. Signed-off-by: Steven A.

| * mpc8641: fix address-cells default in old .dts detectionBecky Bruce2008-11-11-3/+3
| | | | | | | | | | | | | | | | address-cells defaults to 2, not 1; so in the unlikely event that it isn't specified, this patch is required for correct operation. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
| * lib_ppc: Move trap_init to occur earlierBecky Bruce2008-11-10-5/+5
| | | | | | | | | | | | | | | | | | | | | | Doing trap_init immediately once we're running from RAM means we're no longer dependent on the physical location of the flash on non-BookE platforms. Before trap_init, those platforms switch to real mode and go to 0xfff00100 on exception. After the switch, they go to 0x00000100 This makes it easier to move the flash location.

| * mpc8641: Try to detect old .dts filesBecky Bruce2008-11-10-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | Since we've changed the memory map of the board, be nice and add some checking to try to catch out-of-date .dts files. We do this by checking the CCSRBAR location in the .dts and comparing it to the CCSRBAR location in u-boot. If they don't match, a warning msg is printed. This isn't foolproof, but it's simple and will catch most of the cases where an out-of-date .dts is present, including all of the cases where a new u-boot is used with an old standard MPC8641 .dts file as supplied with Linux.

| * mpc8641: Support 36-bit physical addressingBecky Bruce2008-11-10-53/+192
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch creates a memory map with all the devices in 36-bit physical space, in addition to the 32-bit map. The CCSR relocation is moved (again, sorry) to allow for the physical address to be 36 bits - this requires translation to be enabled. With 36-bit physical addressing enabled, we are no longer running with VA=PA translations. This means we have to distinguish between the two in the config file. The existing region name is used to indicate the virtual address, and a _PHYS variety is created to represent the physical address. Large physical addressing is not enabled by default. Set CONFIG_PHYS_64BIT in the config file to turn this on. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
| * mpc8641: Change 32-bit memory mapBecky Bruce2008-11-10-68/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The memory map on the 8641hpcn is modified to look more like the 85xx boards; this is a step towards a more standardized layout going forward. As part of this change, we now relocate the flash. The regions for some of the mappings were far larger than they needed to be. I have reduced the mappings to match the actual sizes supported by the hardware. In addition I have removed the comments at the head of the BAT blocks in the config file, rather than updating them. These get horribly out of date, and it's a simple matter to look at the defines to see what they are set to since everything is right here in the same file. Documentation has been changed to reflect the new map, as this change is user visible, and affects the OS which runs post-uboot. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
| * mpc86xx: Change early FLASH mapping to 1M at CONFIG_MONITOR_BASE_EARLYBecky Bruce2008-11-10-11/+39
| | | | | | | | | | | | | | | | | | | | | | We define CONFIG_MONITOR_BASE_EARLY to define the initial location of the bootpage in flash. Use this to create an early mapping definition for the FLASH, and change the early_bats code to use this. This change facilitates the relocation of the flash since the early mappings are no longer tied to the final location of the flash. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
| * mpc86xx: Use SRR0/1/rfi to enable address translation, not blrBecky Bruce2008-11-10-11/+8
| | | | | | | | | | | | | | | | | | | | Using a mtmsr/blr means that you have to be executing at the same virtual address once you enable translation. This is unnecessarily restrictive, and is not really how this is usually done. Change it to use the more common mtspr SRR0/SRR1 and rfi method. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>

| | | | | | | | | | | | | | | | | | There's a lot of setup and foo for the second flash bank. The problem is, this board doesn't actually have one. Clean this up. Also, the flash is 8M in size.

| | | | | | | | | | | | | | | | | | | | | | In order to later allow for a physical relocation of the flash, setup_bats, which sets up the final BAT mapping for the board, needs to happen *after* init_laws(). Otherwise, there will be no window programmed for the flash at the new physical location at the point when we change the mmu translation. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>

| * | 8641HPCN: Config file cleanupBecky Bruce2008-11-03-5/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are several items in the config file that were hardcoded but that should really be based on other config options, since the regions are contiguous and depend on being so. This cleans that up a bit. Also, add BR_PHYS_ADDR() macro to convert addresses into the proper format for BR registers. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>

| * | powerpc 86xx: Handle CCSR relocation earlierBecky Bruce2008-11-03-16/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the CCSR gets relocated while translation is enabled, meaning we need 2 BAT translations to get to both the old location and the new location. Also, the DEFAULT CCSR location has a dependency on the BAT that maps the FLASH region. Moving the relocation removes this unnecessary dependency. This makes it easier and more intutive to modify the board's memory map. Swap BATs 3 and 4 on 8610 so that all 86xx boards use the same BAT for CCSR space.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | You can't actually have both, and with some coming changes to change the memory map for the board and support 36-bit physical, we need the extra BAT that is being consumed by having both.
