2010-10-04ppc4xx: Use common ns16550 functions in 4xx UART POST driverStefan Roese
This patch changes the PPC4xx POST UART driver to use the common NS16550 functions for receiving and sending. Additionally the local function for SoC divisor setup are removed. Instead the functions from arch/powerpc/cpu/ppc4xx/4xx_uart.c are used. This removes code duplication. Also the common CONFIG_SYS_NS16550_COMx defines are now used to describe the POST UART's. And a compile breakage is fixed, introduced by a git merge of the ppc4xx/next branch into master. Now "ppc4xx.h" is moved to "asm/ppc4xx.h". Fixed as well with this patch.

2010-09-23ppc4xx: POST UART: Use in/out_8() io-accessor functionsStefan Roese
This patch fixes a problem in the PPC4xx POST UART driver. This driver incorrectly used the in/out8() io-accessor functions. This could lead to problems since these functions don't guarantee execution ordering. This patch now replaces these functions with the correct ones. Additionally the driver is converted to using the NS16550 struct instead of macros for the register offsets. And some common code is factored out for better maintainability.

2009-09-11ppc4xx: Big cleanup of PPC4xx definesStefan Roese
This patch cleans up multiple issues of the 4xx register (mostly DCR, SDR, CPR, etc) definitions: - Change lower case defines to upper case (plb4_acr -> PLB4_ACR) - Change the defines to better match the names from the user's manuals (e.g. cprpllc -> CPR0_PLLC) - Removal of some unused defines Please test this patch intensive on your PPC4xx platform. Even though I tried not to break anything and tested successfully on multiple 4xx AMCC platforms, testing on custom platforms is recommended. Signed-off-by: Stefan Roese <sr@denx.de>

2008-06-06ppc4xx: Fix misspelled CONFIG_440SPE/440EPX/GRX config optionsStefan Roese
We use upper case letters for the AMCC processor defines (like CONFIG_440SPE) in U-Boot. So the 440SPe is labeled CONFIG_440SPE and not CONFIG_440SPe. This patch fixes the last misspelled config options. Signed-off-by: Stefan Roese <sr@denx.de>
