* config: Add a default CONFIG_SYS_PROMPTRob Herring2013-11-041-1/+0
| | | | | | | | | | The definitions for CONFIG_SYS_PROMPT are varied with little reason other than to display the board name. Over half the definitions are "==> ", so make this the default. The rest of the boards remain unchanged to avoid breaking any external scripts expecting a certain prompt.

* pci: introduce CONFIG_PCI_INDIRECT_BRIDGE optionGabor Juhos2013-06-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The pci_indirect.c file is always compiled when CONFIG_PCI is defined although the indirect PCI bridge support is not needed by every board. Introduce a new CONFIG_PCI_INDIRECT_BRIDGE config option and only compile indirect PCI bridge support if this options is enabled. Also add the new option into the configuration files of the boards which needs that. Compile tested for powerpc, x86, arm and nds32.

* fsl: Change fsl_phy_enet_if to phy_interface_tAndy Fleming2011-04-201-2/+2
| | | | | | | | | | | | The fsl_phy_enet_if enum was, essentially, the phy_interface_t enum. This meant that drivers which used fsl_phy_enet_if to deal with PHY interfaces would have to convert between the two (or we would have to have them mirror each other, and deal with the ensuing maintenance headache). Instead, we switch all clients of fsl_phy_enet_if over to phy_interface_t, which should become the standard, anyway.

* Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated valueWolfgang Denk2010-10-261-2/+1
| | | | | | | | | | | | | | | | | | CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not being able to use "sizeof(struct global_data)" in assembler files. Recent experience has shown that manual synchronization is not reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into GENERATED_GBL_DATA_SIZE which gets automatically generated by the asm-offsets tool. In the result, all definitions of this value can be deleted from the board config files. We have to make sure that all files that reference such data include the new <asm-offsets.h> file. No other changes have been done yet, but it is obvious that similar changes / simplifications can be done for other, related macro definitions as well.

Note that the code for the PATI and cmi_mpc5xx board configurations looks seriously broken.

Note that this change makes the board info bd_bootflags field useless. It will always be set to 0, but we leave it around so that we don't break the board info structure that some OSes are expecting to be passed from U-Boot.

* e300: increase CONFIG_SYS_BOOTMAPSZ to allow booting large kernelsIra W. Snyder2010-09-231-2/+2
| | | | | | | | | | | | | | Newer Linux kernels can overrun the initial memory window used for booting with their BSS area. When this happens, they overwrite the FDT and silently fail to boot. On e300 CPUs, the Linux kernel uses an initial BAT covering the first 256MB of RAM. See arch/powerpc/kernel/head_32.S for details. Increase the value of CONFIG_SYS_BOOTMAPSZ to accommodate the maximum value allowed by Linux. This will allow very large kernels to boot. Signed-off-by: Ira W.

| | | | | | | | | | | | | | | | | | 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>
