2008-05-21Big white-space cleanup.Wolfgang Denk
This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>

2008-05-08ppc4xx: Add weak default ft_board_setup() routineStefan Roese
This patch adds a default ft_board_setup() routine to the 4xx fdt code. This routine is defined as weak and can be overwritten by a board specific one if needed. Signed-off-by: Stefan Roese <sr@denx.de>

2008-04-30ppc4xx: Fix problem with DIMMs with 8 banks in 44x_spd_ddr2.cStefan Roese
This patch fixes a problem with DIMMs that have 8 banks. Now the MCIF0_MBxCF register will be setup correctly for this setup too. This was noticed with the 512MB DIMM on Canyonlands/Glacier. Signed-off-by: Stefan Roese <sr@denx.de>

2008-04-29ppc4xx: Complete remove bogus dflush()Stefan Roese
Since the current dflush() implementation is know to have some problems (as seem on lwmon5 ECC init) this patch removes it completely and replaces it by using clean_dcache_range(). Tested on Katmai with ECC DIMM. Signed-off-by: Stefan Roese <sr@denx.de>
2008-04-29ppc4xx: Fixup ebc clock in FDT for 405GP/EPMarkus Brunner
On ppc405EP and ppc405GP (at least) the ebc is directly attached to the plb and not to the opb. This patch will try to fixup /plb/ebc if /plb/opb/ebc doesn't exist. Signed-off-by: Markus Brunner <super.firetwister@gmail.com>

2008-04-25ppc4xx: Pass PCIe root-complex/endpoint configuration to Linux via the fdtStefan Roese
The PCIe root-complex/endpoint setup as configured via the "pcie_mode" environment variable will now get passed to the Linux kernel by setting the device_type property of the PCIe device tree node. For normal root- complex configuration it will keep its defaults value of "pci" and for endpoint configuration it will get changed to "pci-endpoint". Signed-off-by: Stefan Roese <sr@denx.de>
2008-04-22ppc4xx: Add dcache_enable() for 440Stefan Roese
dcache_enable() was missing for 440 and the patch 017e9b7925f74878d0e9475388cca9bda5ef9482 ["allow ports to override bootelf "] behavior uses this function. Note: Currently the cache handling functions like d/icache_disable/enable() are NOP's on 440. This may be changed in the future. Signed-off-by: Stefan Roese <sr@denx.de>
2008-04-21ppc4xx: Fix sys_get_info() for 405GP(r)Matthias Fuchs
This patch assigns the correct EBC clock for 405GP(r) CPUs to PPC4xx_SYS_INFO structure. Without this patch U-Boot uses an uninitialized EBC clock in its startup message. Signed-off-by: Matthias Fuchs <matthias.fuchs@esd-electronics.com>
2008-04-18Fix crash on sequoia in ppc_4xx_eth_initAnatolij Gustschin
Currently U-Boot crashes in ppc_4xx_eth_init on sequoia with cache enabled (TLB Parity exeption). This patch fixes the problem. Signed-off-by: Anatolij Gustschin <agust@denx.de>
2008-04-18ppc4xx: Fix crash on sequoia with cache enabledAnatolij Gustschin
Currently U-Boot crashes on sequoia board in CPU POST if cache is enabled (CONFIG_4xx_DCACHE defined). The cache won't be disabled by change_tlb before CPU POST because there is an insufficient adress range check since CFG_MEM_TOP_HIDE was introduced. This patch tries to fix this problem.

2008-04-03ppc4xx: Fix 4xx enet driver to support 460GT EMAC2+3Stefan Roese
This patch fixes a problem with the RGMII setup of the 460GT. The 460GT has 2 RGMII instances and we need to configure the 2nd RGMII instance for the EMAC2+3 channels. Signed-off-by: Stefan Roese <sr@denx.de>

2008-03-27ppc4xx: PPC405EP Set EMAC noise filter bitsMarkus Brunner
This bug was introduced with commit aee747f19b460a0e9da20ff21e90fdaac1cec359 which enabled CFG_4xx_GPIO_TABLE for PPC405 and unintentionally disabled the setting of the emac noise filter bits for PPC405EP when CFG_4xx_GPIO_TABLE is set.

2008-03-27ppc4xx: Reconfigure PLL for 667MHz processor for PPC440EPxMike Nuss
On PPC440EPx without a bootstrap I2C EEPROM, the PLL can be reconfigured after startup to change the speed of the clocks. This patch adds the option CFG_PLL_RECONFIG. If this option is set to 667, the CPU initialization code will reconfigure the PLL to run the system with a CPU frequency of 667MHz and PLB frequency of 166MHz, without the need for an external EEPROM.

2008-03-27ppc4xx: Add AMCC Glacier 406GT eval board supportStefan Roese
This patch adds support for the AMCC Glacier 460GT eval board. The main difference to the Canyonlands board are listed here: - 4 ethernet ports instead of 2 - no SATA port - no USB port Currently EMAC2+3 are not working. This will be fixed in a later release.

2008-03-15ppc4xx: Add Canyonlands NAND booting supportStefan Roese
460EX doesn't support a fixed bootstrap option to boot from 512 byte page NAND devices. The only bootstrap option for NAND booting is option F for 2k page devices. So to boot from a 512 bype page device, the I2C bootstrap EEPROM needs to be programmed accordingly. This patch adds basic NAND booting support for the AMCC Canyonlands aval board and also adds support to the "bootstrap" command, to enable NAND booting I2C setting. Tested with 512 byte page NAND device (32MByte) on Canyonlands. Signed-off-by: Stefan Roese <sr@denx.de>
2008-03-15ppc4xx: Add basic support for AMCC 460EX/460GT (2/5)Stefan Roese

2008-03-15ppc4xx: interrupt.c reworkedStefan Roese
This patch is a rework of the 4xx interrupt handling done while adding the 460EX/GT support. Interrupts are needed on 4xx for the EMAC driver. Signed-off-by: Stefan Roese <sr@denx.de>
2008-03-15ppc4xx: program_tlb now uses 64bit physical addessStefan Roese
This patch changes the physical addess parameter from 32bit to 64bit. This is needed for 36bit 4xx platforms to access areas located beyond the 4GB border, like SoC peripherals (EBC etc.). Signed-off-by: Stefan Roese <sr@denx.de>

2008-03-04PPC4xx (Sequoia): Fix Ethernet "remote fault" problemsMike Nuss
Every now and then a Sequoia board (or equivalent hardware) had problems connecting to a Gigabit capable network interface. There were differences in the PHY setup between Linux and U-Boot. This patch fixes the problem. Apparently "remote fault" is being set, which signals to some devices (on the other end of the cable) that a fault has occurred, while other devices ignore it. I believe the RF bit was causing the issue, but I removed T4 also, to match up with Linux. Signed-off-by: Mike Nuss <mike@terascala.com>
2008-03-02ppc4xx: EMAC: Fix 405EZ fifo size setup in EMAC_MR1Stefan Roese
The 405EZ only supports 512 bytes of rx-/tx-fifo EMAC sizes. But currently 4k/2k is configured. This patch fixes this issue. Thanks to Thomas Kindler <tkindler@lenord.de> for pointing this out. Signed-off-by: Stefan Roese <sr@denx.de>
2008-03-02ppc4xx: Fix problem in 4xx_enet.c driverAnatolij Gustschin
U-Boot crashes in the net loop if CONFIG_4xx_DCACHE is enabled. To reproduce the problem ensure that 'ethrotate' environment variable isn't set to "no" and then run "tftp 200000 not_existent_file". This patch tries to fix the issue. Signed-off-by: Anatolij Gustschin <agust@denx.de>

2008-02-14PPC: Use r2 instead of r29 as global data pointerWolfgang Denk
R29 was an unlucky choice as with recent toolchains (gcc-4.2.x) gcc will refuse to use load/store multiple insns; instead, it issues a list of simple load/store instructions upon function entry and exit, resulting in bigger code size, which in turn makes the build for a few boards fail. Use r2 instead. Signed-off-by: Wolfgang Denk <wd@denx.de>

2008-02-04ppc4xx: Fix ndfc HW ECC byte orderStefan Roese
The current ndfc HW ECC implementation swaps the first two ECC bytes. But the 4xx NDFC already uses the SMC (Smart Media Card) ECC ordering, so this swapping in the HW ECC driver is bogus. This patch fixes this problem and now really uses the SMC ECC byte order. Thanks to Sean MacLennan for pointing this out. Signed-off-by: Stefan Roese <sr@denx.de>

2008-01-09ppc4xx: Add CFG_POST_ALT_WORD_ADDR to support non OCM POST WORD storageStefan Roese
The privious 4xx POST implementation only supported storing the POST WORD in OCM. Since we need to reserve the OCM on LWMON5 for the logbuffer we need to store the POST WORD in some other non volatile location. This patch adds CFG_POST_ALT_WORD_ADDR to specify an address for such a location. Signed-off-by: Stefan Roese <sr@denx.de>
2008-01-09ppc4xx: Add 44x cache locking to better support init-ram in d-cacheStefan Roese
This patch adds support for locking the init-ram/stack in d-cache, so that other regions may use d-cache as well Note, that this current implementation locks exactly 4k of d-cache, so please make sure that you don't define a bigger init-ram area. Take a look at the lwmon5 440EPx implementation as a reference. Signed-off-by: Stefan Roese <sr@denx.de>
