| | | | | | | | | | | | Up to now, the function is_serdes_configed() doesn't check if the map of serdes protocol is initialized before accessing it. The function is_serdes_configed() will get wrong result when it was called before the serdes protocol maps initialized. As the first element of the map isn't used for any device, so use it as the flag to indicate if the map has been initialized.

| | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds: - arch/${ARCH}/Kconfig provide a menu to select target boards - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig set CONFIG macros to the appropriate values for each board - configs/${TARGET_BOARD}_defconfig default setting of each board (This commit was automatically generated by a conversion script based on boards.cfg) In Linux Kernel, defconfig files are located under arch/${ARCH}/configs/ directory. It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.

* 8xxx: Change all 8*xx_DDR addresses to 8xxxAndy Fleming2012-11-27-2/+2
| | | | | | | | | | | | | | | | | | | | | | There were a number of shared files that were using CONFIG_SYS_MPC85xx_DDR_ADDR, or CONFIG_SYS_MPC86xx_DDR_ADDR, and several variants (DDR2, DDR3). A recent patchset added 85xx-specific ones to code which was used by 86xx systems. After reviewing places where these constants were used, and noting that the type definitions of the pointers assigned to point to those addresses were the same, the cleanest approach to fixing this problem was to unify the namespace for the 85xx, 83xx, and 86xx DDR address definitions. This patch does: s/CONFIG_SYS_MPC8.xx_DDR/CONFIG_SYS_MPC8xxx_DDR/g All 85xx, 86xx, and 83xx have been built with this change.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Boot space translation utilizes the pre-translation address to select the DDR controller target. However, the post-translation address will be presented to the selected DDR controller. It is possible that the pre- translation address selects one DDR controller but the post-translation address exists in a different DDR controller when using certain DDR controller interleaving modes. The device may fail to boot under these circumstances. Note that a DDR MSE error will not be detected since DDR controller bounds registers are programmed to be the same when configured for DDR controller interleaving.

* powerpc/mpc86xx: Disable translation for BAT setupBecky Bruce2011-10-09-29/+68
| | | | | | | | | | | | | | | | | We really shouldn't be overwriting bat registers with translation enabled, especially when we're executing code using one of them for translating the current instruction stream. Instead, disable address translation while doing the final BAT setup. In order to do this, setup_bats has to move back to asm code, because we require translation to be enabled to have a stack for C code. The yucky thing about that is that the assembler doesn't like ULL so we have to switch to using HIGH/LOW pairs for physical addresses that are > 32 bits in length.

* mpc8[5/6]xx: Ensure POST word does not get resetJohn Schmoller2011-03-13-0/+16
| | | | | | | | | | | | The POST word is stored in a spare register in the PIC on MPC8[5/6]xx processors. When interrupt_init() is called, this register gets reset which resulted in all POST_RAM POSTs not being ran due to the corrupted POST word. To resolve this, store off POST word before the PIC is reset, and restore it after the PIC has been initialized.
