* 85xx: init gd as early as possibleKumar Gala2008-12-04-6/+6
| | | | | | | | Moved up the initialization of GD so C code like set_tlb() can use gd->flags to determine if we've relocated or not in the future. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Andy Fleming <afleming@freescale.com>
* 85xx: Fix relocation of CCSRBARKumar Gala2008-12-04-4/+5
| | | | | | | | | | If the virtual address for CCSRBAR is the same after relocation but the physical address is changing we'd end up having two TLB entries with the same VA. Instead we new us the new CCSRBAR virt address + 4k as a temp virt address to access the old CCSRBAR to relocate it.

* 85xx: Add CPU 2 errata workaround to all 8548 boardsPeter Tyser2008-12-03-0/+13
| | | | | | | | | | | All mpc8548-based boards should implement the suggested workaround to CPU 2 errata. Without the workaround, its possible for the 8548's core to hang while executing a msync or mbar 0 instruction and a snoopable transaction from an I/O master tagged to make quick forward progress is present.

* 85xx: Fix the incorrect register used for DDR erratum1Dave Liu2008-10-24-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 8572 DDR erratum1: DDR controller may enter an illegal state when operating in 32-bit bus mode with 4-beat bursts. Description: When operating with a 32-bit bus, it is recommended that DDR_SDRAM_CFG[8_BE] is cleared when DDR2 memories are used. This forces the DDR controller to use 4-beat bursts when communicating to the DRAMs. However, an issue exists that could lead to data corruption when the DDR controller is in 32-bit bus mode while using 4-beat bursts. Projected Impact: If the DDR controller is operating in 32-bit bus mode with 4-beat bursts, then the controller may enter into a bad state. All subsequent reads from memory is corrupted. Four-beat bursts with a 32-bit bus only is used with DDR2 memories. Therefore, this erratum does not affect DDR3 mode. Work Arounds: To work around this issue, software must set DEBUG_1[31] in DDR memory mapped space (CCSRBAR offset + 0x2f00 for DDR_1 and CCSRBAR offset + 0x6f00 for DDR_2). Currenlty, the code is using incorrect register DDR_SDRAM_CFG_2 as condition, but it should be DDR_SDRAM_CFG register. Signed-off-by: Dave Liu <daveliu@freescale.com>

* | Revert "85xx: Using proper I2C source clock divider for MPC8544"Kumar Gala2008-10-17-2/+2
|/ | | | | | | | | | This reverts commit dffd2446fb041f38ef034b0fcf41e51e5e489159. The fix introduced by this patch is not correct. The problem is that the documentation is not correct for the MPC8544 with regards to which bit in PORDEVSR2 is for the SEC_CFG. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* 85xx: Using proper I2C source clock divider for MPC8544Wolfgang Grandegger2008-10-08-2/+2
| | | | | | | | | Measurements with our MPC8544 board showed that the I2C bus frequency is wrong by a factor of 1.5. Obviously, the interpretation of the MPC85xx_PORDEVSR2_SEC_CFG bit of the cfg_sec_freq register is not correct. There seems to be an error in the 8544 RM.

* Pass in tsec_info struct through tsec_initializeAndy Fleming2008-09-02-23/+10
| | | | | | | | | | | | | The tsec driver contains a hard-coded array of configuration information for the tsec ethernet controllers. We create a default function that works for most tsecs, and allow that to be overridden by board code. It creates an array of tsec_info structures, which are then parsed by the corresponding driver instance to determine configuration. Also, add regs, miiregs, and devname fields to the tsec_info structure, so that we don't need the kludgy "index" parameter.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The main purpose of this rewrite it to be able to share the same initialization code on all FSL PowerPC products that have DDR controllers. (83xx, 85xx, 86xx). The code is broken up into the following steps: GET_SPD COMPUTE_DIMM_PARMS COMPUTE_COMMON_PARMS GATHER_OPTS ASSIGN_ADDRESSES COMPUTE_REGS PROGRAM_REGS This allows us to share more code an easily allow for board specific code overrides. Additionally this code base adds support for >4G of DDR and provides a foundation for supporting interleaving on processors with more than one controller.

* Fix printf errors.Andrew Klossner2008-07-09-4/+4
| | | | | | | | | | | | The compiler will help find mismatches between printf formats and arguments if you let it. This patch adds the necessary attributes to declarations in include/common.h, then begins to correct the resulting compiler warnings. Some of these were bugs, e.g., "$d" instead of "%d" and incorrect arguments. Others were just annoying, like int-long mismatches on a system where both are 32 bits. It's worth fixing the annoying errors to catch the real ones. Signed-off-by: Andrew Klossner <andrew@cesa.opbu.xerox.com>
