| * libfdt: Several cleanups to parameter checkingDavid Gibson2008-06-09-55/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes a couple of small cleanups to parameter checking of libfdt functions. - In several functions which take a node offset, we use an idiom involving fdt_next_tag() first to check that we have indeed been given a node offset. This patch adds a helper function _fdt_check_node_offset() to encapsulate this usage of fdt_next_tag(). - In fdt_rw.c in several places we have the expanded version of the RW_CHECK_HEADER() macro for no particular reason. This patch replaces those instances with an invocation of the macro; that's what it's for. - In fdt_sw.c we rename the check_header_sw() function to sw_check_header() to match the analgous function in fdt_rw.c, and we provide an SW_CHECK_HEADER() wrapper macro as RW_CHECK_HEADER() functions in fdt_rw.c Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

They do not disagree, but only 1 Application Note noted explicitly that only these 2 bits need to be checked. Even the datasheets do not mention anything about these 2 bits. Because the old code, and the kernel check the whole byte, I left this piece untouched. However, I tested all board/DM9000[A|E|EP] devices with this 2 bit check, so it should work. Notice, that the 2nd iteration through this receive loop (when a 2nd packet is in the fifo) is much shorter now, compared to the older U-boot driver code, so that we can maybe run into a hardware condition now that was never seen before, or maybe was seen very unfrequently. Additionaly added a cleanup of a stack variable. Signed-off-by: Remy Bohmer <linux@bohmer.net> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
| * | | Get rid of annoying/superfluous bad-checksum warning messageRemy Bohmer2008-06-04-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | U-boot can complain a lot about 'checksum bad' when it is attached to the network. It is annoying for ordinary users who start to doubt the network connection in general when they see messages like this. This is caused by the routine NetCksumOk() which cannot handle IP-headers longer than 20 bytes. Those packages can be ignored anyway by U-boot, so we trash them now before checking the checksum.

Analysis showed that many incoming packets are lost. The DM9000A Application Notes V1.20 (section 5.6.1) recommend that the poll to check for a valid rx packet be done on the interrupt status register, not directly by performing the dummy read and the rx status check as is currently the case in the u-boot driver. When the recommended poll is done as suggested the driver starts working correctly on 10Mbit/HD, but on 100MBit/FD packets come in faster so that there can be more than 1 package in the fifo at the same time. The driver must perform the rx-status check in a loop and read and handle all packages until there is no more left _after_ the interrupt RX flag is set.

This compile check makes the code unclear, inflexible and is unneccessary. It can be asked to the network controller what its bus-width is by reading bits 6 and 7 of the interrupt status register. The linux kernel already uses a runtime mechanism to determine this bus-width, so the implementation below looks somewhat like that implementation.

This function was still called from start.S and most of the time coded in assembler. This is not needed anymore (since a long time) and boards should implement the common initdram() function in C instead. This patch now removed the dram_init() call from start.S and removes the empty implementations that are scattered through most of the 405 board ports. Some older board ports really implement this dram_init() though. These are: csb272 csb472 ERIC EXBITGEN W7OLMC W7OLMG I changed those boards to call this assembler dram_init() function now from their board specific initdram() instead. This *should* work, but please test again on those platforms. And it is perhaps a good idea that those boards use some common 405 SDRAM initialization code from cpu/ppc4xx at some time. So further patches welcome here. Signed-off-by: Stefan Roese <sr@denx.de>

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>

Now common code is used to initialize the SDRAM by calling initdram() and to "copy/relocate" to SDRAM/OCM/etc. Only *after* running from this location, nand_boot() is called. Please note that the initsdram() call is now moved from nand_boot.c to start.S. I experienced problems with some boards like Kilauea (405EX), which don't have internal SRAM (OCM) and relocation needs to be done to SDRAM before the NAND controller can get accessed. When initdram() is called later on in nand_boot(), this can lead to problems with variables in the bss sections like nand_ecc_pos[].

| * | | | ppc4xx: Enable Primordial Stack for 40x and Unify ECC HandlingGrant Erickson2008-06-03-444/+330
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (Part 2 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.
