* mpc86xx: set the DDR BATs after calculating true DDR sizeTimur Tabi2010-03-30-1/+5
| | | | | | | | | | | | | | | | | | | | After determining how much DDR is actually in the system, set DBAT0 and IBAT0 accordingly. This ensures that the CPU won't attempt to access (via speculation) addresses outside of actual memory. On 86xx systems, DBAT0 and IBAT0 (the BATs for DDR) are initialized to 2GB and kept that way. If the system has less than 2GB of memory (typical for an MPC8610 HPCD), the CPU may attempt to access this memory during speculation. The zlib code is notorious for generating such memory reads, and indeed on the MPC8610, uncompressing the Linux kernel causes a machine check (without this patch). Currently we are limited to power of two sized DDR since we only use a single bat. If a non-power of two size is used that is less than CONFIG_MAX_MEM_MAPPED u-boot will crash.

* 85xx: Fix enabling of L1 cache parity on secondary coresKumar Gala2010-03-30-0/+2
| | | | | | | | | | | Use the same code between primary and secondary cores to init the L1 cache. We were not enabling cache parity on the secondary cores. Also, reworked the L1 cache init code to match the e500mc L2 init code that first invalidates the cache and locks. Than enables the cache and makes sure its enabled before continuing.

* 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.

* 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>
