* Dual-license IBM code contributionsJosh Boyer2009-08-09-0/+2
| | | | | | | | | | | | | It was brought to our attention that U-Boot contains code derived from the IBM OpenBIOS source code originally provided with some of the older PowerPC 4xx development boards. As a result, the original license of this code has been carried in the various files for a number of years in the U-Boot project. IBM is dual-licensing the IBM code contributions already present in U-Boot under either the terms of the GNU General Public License version 2, or the original code license already present.

* ppc4xx: Move definition for PPC4xx NAND FLASH controller to headerStefan Roese2009-05-23-0/+7
| | | | | | | | | This patch moves the definition for the PPC4xx NAND FLASH controller (NDFC) CONFIG_NAND_NDFC into include/ppc4xx.h. This is needed for the upcoming fix for the ECC byte ordering of the NDFC driver. Signed-off-by: Stefan Roese <sr@denx.de> Acked-by: Scott Wood <scottwood@freescale.com>
* ppc4xx: Add routine to retrieve CPU numberAdam Graham2008-10-21-0/+3
| | | | | | | | | | | | Provide a weak defined routine to retrieve the CPU number for reference boards that have multiple CPU's. Default behavior is the existing single CPU print output. Reference boards with multiple CPU's need to provide a board specific routine. See board/amcc/arches/arches.c for an example.

* ppc4xx: Cleanup of "ppc4xx: Optimize PLB4 Arbiter..." patchStefan Roese2008-08-21-12/+12
| | | | | | | | | | | | | This patch fixes some minor issues introduced with the patch: ppc4xx: Optimize PLB4 Arbiter... from Prodyut Hazarika: - Rework memory-queue and PLB arbiter optimization code, that the local variable is not needed anymore. This removes one #ifdef. - Use consistant spacing in ppc4xx.h header (XXX + 0x01 instead of XXX+ 0x01). This was not introduced by Prodyut, just a copy-paste problem.

* ppc4xx: Consolidate PPC4xx UIC definesStefan Roese2008-07-11-0/+1
| | | | | | | | | This patch is the first step to consolidate the UIC related defines in the 4xx headers. Move header from asm-ppc/ppc4xx-intvec.h to asm-ppc/ppc4xx-uic.h as it will hold all UIC related defines in the next steps. Signed-off-by: Stefan Roese <sr@denx.de>

* ppc4xx: Consolidate PPC4xx SDRAM/DDR/DDR2 defines, part1Stefan Roese2008-06-03-0/+25
| | | | | | | | | | | | | | | | | | | This patch removes all SDRAM related defines from the PPC4xx headers ppc405.h and ppc440.h. This is needed since now some 405 PPC's use the same SDRAM controller as 440 systems do (like 405EX and 440SP). It also introduces new defines for the equipped SDRAM controller based on which PPC variant is used. There new defines are: used on 405GR/CR/EP and some Xilinx Virtex boards. used on 440GP/GX/EP/GR. used on 440EPx/GRx. used on 405EX/r/440SP/SPe/460EX/GT. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Enable Primordial Stack for 40x and Unify ECC HandlingGrant Erickson2008-06-03-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (Part 1 of 2): * Rolls up a suite of changes to enable correct primordial stack and global data handling when the data cache is used for such a purpose for PPC40x-variants (i.e. CFG_INIT_DCACHE_CS). * Related to the first, unifies DDR2 SDRAM and ECC initialization by eliminating redundant ECC initialization implementations and moving redundant SDRAM initialization out of board code into shared 4xx code. * Enables MCSR visibility on the 405EX(r). * Enables the use of the data cache for initial RAM on both AMCC's Kilauea and Makalu and removes a redundant CFG_POST_MEMORY flag from each board's CONFIG_POST value. - Removed, per Stefan Roese's request, defunct memory.c file for Makalu and rolled sdram_init from it into makalu.c. With respect to the 4xx DDR initialization and ECC unification, there is certainly more work that can and should be done (file renaming, etc.). However, that can be handled at a later date on a second or third pass. As it stands, this patch moves things forward in an incremental yet positive way for those platforms that utilize this code and the features associated with it.

* ppc4xx: Consolidate some of the 405 and 440 macros/structs into 4xxStefan Roese2007-10-31-3/+70
| | | | | | | | | | This patch moves some common 4xx macros and the PPC405_SYS_INFO/ PPC440_SYS_INFO structure into the common ppc4xx.h header. Lot's of other macros are good candidates to be consolidated this way in the future. Signed-off-by: Stefan Roese <sr@denx.de>

| | | | | | | | | | | | | | | | | | | | | | - Introduced dedicated switches for building 440 and 405 images required for 440-specific machine instructions like 'rfmci' etc. - Exception vectors moved to the proper location (_start moved away from the critical exception handler space, which it occupied) - CriticalInput now serviced (with default handler) - MachineCheck properly serviced (added a dedicated handler and return subroutine) - Overall cleanup of exceptions declared with STD_EXCEPTION macro (unused, unhandled and those not relevant for 4xx were eliminated) - Eliminated Linux leftovers, removed dead code Signed-off-by: Grzegorz Bernacki <gjb@semihalf.com> Signed-off-by: Rafal Jaworowski <raj@semihalf.com> Signed-off-by: Stefan Roese <sr@denx.de>
