* i2c: merge all i2c_reg_read() and i2c_reg_write() into inline functionsTimur Tabi2008-12-15-20/+0
| | | | | | | | | | All implementations of the functions i2c_reg_read() and i2c_reg_write() are identical. We can save space and simplify the code by converting these functions into inlines and putting them in i2c.h.

* ppc4xx: Changed 460EX/GT OCM TLB and internal SRAM initializationDave Mitchell2008-11-21-7/+20
| | | | | | | | | | | | | | | | | | 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: Generic architecture for xilinx ppc405(v3)Ricardo Ribalda Delgado2008-10-24-1/+2
| | | | | | | | | | | | | | | | | As "ppc44x: Unification of virtex5 pp440 boards" did for the xilinx ppc440 boards, this patch presents a common architecture for all the xilinx ppc405 boards. Any custom xilinx ppc405 board can be added very easily with no code duplicity. This patch also adds a simple generic board, that can be used on almost any design with xilinx ppc405 replacing the file ppc405-generic/xparameters.h This patch is prepared to work with the latest version of EDK (10.1) Signed-off-by: Ricardo Ribalda Delgado <ricardo.ribalda@uam.es> Signed-off-by: Stefan Roese <sr@denx.de>

| * | ppc4xx: PPC44x MQ initializationYuri Tikhonov2008-10-17-4/+6
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Set the MQ Read Passing & MCIF Cycle limits to the recommended by AMCC values. This fixes the occasional 440SPe hard locking issues when the 440SPe's dedicated DMA engines are used (e.g. by the h/w accelerated RAID driver). Previously the appropriate initialization had been made in Linux, by the ppc440spe ADMA driver, which is wrong because modifying the MQ configuration registers after normal operation has begun is not supported and could have unpredictable results. Comment from Stefan: This patch doesn't change the resulting value of the MQ registers. It explicitly sets/clears all bits to the desired state which better documents the resulting register value instead of relying on pre-set default values.

|/ | | | | | | | | | | | | | At a lot of places in the code the PIPE_INTERRUPT flags and friends are used wrong. The wrong bits are compared to this flag resulting in wrong conditions. Also there are macros that should be used for PIPE_* flags. This patch tries to fix them all, however, I was not able to test the changes, because I do not have any of these boards. Review required!

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Alternate SDRAM DDR autocalibration routine that can be generically used for any PPC4xx chips that have the IBM SDRAM Controller core allowing for support of more DIMM/memory chip vendors and gets the DDR autocalibration values which give the best read latency performance (SDRAM0_RDCC.[RDSS]). Two alternate SDRAM DDR autocalibration algoritm are provided in this patch, "Method_A" and "Method_B". DDR autocalibration Method_A scans the full range of possible PPC4xx SDRAM Controller DDR autocalibration values and takes a lot longer to run than Method_B. Method_B executes in the same amount of time as the currently existing DDR autocalibration routine, i.e. 1 second or so. Normally Method_B is used and it is set as the default method. The current U-Boot PPC4xx DDR autocalibration code calibrates the IBM SDRAM Controller registers.[bit-field]: 1) SDRAM0_RQDC.[RQFD] 2) SDRAM0_RFDC.[RFFD] This alternate PPC4xx DDR autocalibration code calibrates the following IBM SDRAM Controller registers.[bit-field]: 1) SDRAM0_WRDTR.[WDTR] 2) SDRAM0_CLKTR.[CKTR] 3) SDRAM0_RQDC.[RQFD] 4) SDRAM0_RFDC.[RFFD] and will also use the calibrated settings of the above four registers that produce the best "Read Sample Cycle Select" value in the SDRAM0_RDCC.[RDSS] register.[bit-field].

This patch takes U-Boot NAND support to the level of Linux 2.6.22.1 and will enable support for very large NAND devices (4KB pages) and ease the compatibility between U-Boot and Linux filesystems. This patch is tested on two custom boards with PPC and ARM processors running YAFFS in U-Boot and Linux using gcc-4.1.2 cross compilers. MAKEALL ppc/arm has some issues: * DOC/OneNand/nand_spl is not building (I have not tried porting these parts, and since I do not have any HW and I am not familiar with this code/HW I think its best left to someone else.) Except for the issues mentioned above, I have ported all drivers necessary to run MAKEALL ppc/arm without errors and warnings. Many drivers were trivial to port, but some were not so trivial.
