* mpc86xx: set the DDR BATs after calculating true DDR sizeTimur Tabi2010-03-30-0/+4
| | | | | | | | | | | | | | | | | | | | 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.

* 8xxx: Removed CONFIG_NUM_CPUS from 85xx/86xxPoonam Aggrwal2009-08-28-2/+2
| | | | | | | | | | | | | The number of CPUs are getting detected dynamically by checking the processor SVR value. Also removed CONFIG_NUM_CPUS references from all the platforms with 85xx/86xx processors. This can help to use the same u-boot image across the platforms. Also revamped and corrected few Freescale Copyright messages. Signed-off-by: Poonam Aggrwal <poonam.aggrwal@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* 86xx: Cleanup MP supportKumar Gala2009-04-01-1/+1
| | | | | | | | | | | | | | * Use CONFIG_MP instead of CONFIG_NUM_CPUS to match 85xx * Introduce determine_mp_bootpg() helper. We'll need this to address a bug introduced in v2009.03 with 86xx MP booting. We have to make sure to reserve the region of memory used for the MP bootpg() so other u-boot code doesn't use it. * Added dummy versions of cpu_reset(), cpu_status() & cpu_release() to allow cmd_mp.c to build and work. In the future we should look at implementing all these functions. This could be common w/85xx if we use spin tables on 86xx. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* mpc86xx: Add support to populate addr map based on BATsBecky Bruce2009-02-10-0/+27
| | | | | | | If CONFIG_ADDR_MAP is enabled, update the address map whenever we write a bat. Signed-off-by: Becky Bruce <beckyb@kernel.crashing.org>
* mpc86xx: Move setup_bats into cpu_init_fBecky Bruce2008-11-10-0/+4
| | | | | | | | | | | 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>
* powerpc: change 86xx SMP boot methodBecky Bruce2008-11-04-0/+4
| | | | | | | | | We put the bootpg for the secondary cpus into memory and use BPTR to get to it. This is a step towards converting to the ePAPR boot methodology. Also, the code is written to deal properly with more than 4GB of RAM. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>

* POWERPC 86xx: Move BAT setup code to CBecky Bruce2008-08-11-0/+25
| | | | | | | | | | This is needed because we will be possibly be locating devices at physical addresses above 32bits, and the asm preprocessing does not appear to deal with ULL constants properly. We now call write_bat in lib_ppc/bat_rw.c. Signed-off-by: Becky Bruce <becky.bruce@freescale.com> Acked-by: Jon Loeliger <jdl@freescale.com>
* 85xx/86xx: Move to dynamic mgmt of LAWsKumar Gala2008-06-11-3/+0
| | | | | | | | | | | With the new LAW interface (set_next_law) we can move to letting the system allocate which LAWs are used for what purpose. This makes life a bit easier going forward with the new DDR code.
