* i2c, dtt: move dtt_init () to board_init_r ()Heiko Schocher2009-03-02-3/+3

* Add MMC FrameworkAndy Fleming2009-02-16-0/+9
| | | | | | | | | | | | | | Here's a new framework (based roughly off the linux one) for managing MMC controllers. It handles all of the standard SD/MMC transactions, leaving the host drivers to implement only what is necessary to deal with their specific hardware. This also hooks the infrastructure into the PowerPC board code (similar to how the ethernet infrastructure now hooks in) Some of this code was contributed by Dave Liu <daveliu@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>

* SATA: do not auto-initialize during bootMike Frysinger2009-01-27-20/+0
| | | | | | | | | | | | Rather than have the board code initialize SATA automatically during boot, make the user manually run "sata init". This brings the SATA subsystem in line with common U-Boot policy. Rather than having a dedicated weak function "is_sata_supported", people can override sata_initialize() to do their weird board stuff. Then they can call the actual __sata_initialize().

* lib_ppc: Move trap_init to occur earlierBecky Bruce2008-11-10-5/+5
| | | | | | | | | | | Doing trap_init immediately once we're running from RAM means we're no longer dependent on the physical location of the flash on non-BookE platforms. Before trap_init, those platforms switch to real mode and go to 0xfff00100 on exception. After the switch, they go to 0x00000100 This makes it easier to move the flash location.

| * mpc8323erdb: fix EEPROM page size and get MAC from EEPROMMichael Barkowski2008-03-28-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes eeprom page size so that you can now write more than 64 bytes at a time. It also makes the board take MAC addresses, if found, from EEPROM. User should place up to 4 addresses at offset 0x7f00, for eth{,1,2,3}addr. Any unused addresses should be zero. This group of four six-byte values should have it's CRC at the end. crc32 and eeprom commands can be used to accomplish this. If CRC fails, MAC addresses come from the environment. If CRC succeeds, the environment is overwritten at startup. Signed-off-by: Michael Barkowski <michael.barkowski@freescale.com> Signed-off-by: Kim Phillips <kim.phillips@freescale.com>

* | ppc: Add CFG_MEM_TOP_HIDE option to hide memory area that doesn't get "touched"Stefan Roese2008-03-27-0/+13
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If CFG_MEM_TOP_HIDE is defined in the board config header, this specified memory area will get subtracted from the top (end) of ram and won't get "touched" at all by U-Boot. By fixing up gd->ram_size the Linux kernel should gets passed the now "corrected" memory size and won't touch it either. This should work for arch/ppc and arch/powerpc. Only Linux board ports in arch/powerpc with bootwrapper support, which recalculate the memory size from the SDRAM controller setup, will have to get fixed in Linux additionally. This patch enables this config option on some PPC440EPx boards as a workaround for the CHIP 11 errata. Here the description from the AMCC documentation: CHIP_11: End of memory range area restricted access. Category: 3 Overview: The 440EPx DDR controller does not acknowledge any transaction which is determined to be crossing over the end-of-memory-range boundary, even if the starting address is within valid memory space. Any such transaction from any PLB4 master will result in a PLB time-out on PLB4 bus. Impact: In case of such misaligned bursts, PLB4 masters will not retrieve any data at all, just the available data up to the end of memory, especially the 440 CPU. For example, if a CPU instruction required an operand located in memory within the last 7 words of memory, the DCU master would burst read 8 words to update the data cache and cross over the end-of-memory-range boundary. Such a DCU read would not be answered by the DDR controller, resulting in a PLB4 time-out and ultimately in a Machine Check interrupt. The data would be inaccessible to the CPU. Workaround: Forbid any application to access the last 256 bytes of DDR memory. For example, make your operating system believe that the last 256 bytes of DDR memory are absent. AMCC has a patch that does this, available for Linux. This patch sets CFG_MEM_TOP_HIDE for the following 440EPx boards: lwmon5, korat, sequoia The other remaining 440EPx board were intentionally not included since it is not clear to me, if they use the end of ram for some other purpose. This is unclear, since these boards have CONFIG_PRAM defined and even comments like this: PMC440.h: /* esd expects pram at end of physical memory. * So no logbuffer at the moment. */ It is strongly recommended to not use the last 256 bytes on those boards too. Patches from the board maintainers are welcome. Signed-off-by: Stefan Roese <sr@denx.de>

* The patch introduces the alternative configuration of the log buffer for the ↵Yuri Tikhonov2008-03-18-0/+4
| | | | | | | | | | | | | | lwmon5 board: the storage for the log-buffer itself is OCM(on-chip memory), the log-buffer header is moved to six GPT registers (PPC440EPX_GPT0_COMP1, ..., PPC440EPX_GPT0_COMP5). To enable this, alternative, configuration the U-Boot board configuration file for lwmon5 includes the definitions of alternative addresses for header (CONFIG_ALT_LH_ADDR) and buffer (CONFIG_ALT_LB_ADDR). The Linux shall be configured with the CONFIG_ALT_LB_LOCATION option set, and has the BOARD_ALT_LH_ADDR and BOARD_ALT_LB_ADDR constants defined in the lwmon5 board-specific header (arch/ppc/platforms/4xx/lwmon5.h).
