* lpc32xx: remove surplus clock cycle in PL175 WAIT_OEN configVladimir Zapolskiy2015-10-11-1/+1
| | | | | | | | | | | | | | According to ARM PrimeCell PL175 documentation WAIT_OEN config value is defined without any additional clocks added to the value set by a client, the change fixes the wrong interface to WAIT_OEN config. The change also touches a single user of LPC32xx EMC and corrects configured "output enable delay" value on its side according to the changed interface. No functional change intended.

* lpc32xx: devkit3250: add spl build supportVladimir Zapolskiy2015-08-12-0/+69
| | | | | | | | | | | | The change adds SPL build support to Timll DevKit3250 board, the generated SPL image can be uploaded over UART5, JTAG or stored on NAND. SPL is designed to load U-boot image from NAND. All new NAND chip defines in board configuration are needed by SPL NAND "simple" framework, the framework is used to reduce potentially duplicated code from LPC32xx SLC NAND driver.

* lpc32xx: devkit3250: update of board configurationVladimir Zapolskiy2015-08-12-1/+30
| | | | | | | | | | | | This change adds more peripherals to Timll DevKit3250 board, namely MAC and SMSC phy, SLC NAND, GPIO, SPI and I2C. Also the default serial console is changed to UART5, added an option to pass device tree blob by means of bootm, predefined environment variables are slightly extended and reserved space on NAND to store user defined U-boot environment.

* kconfig: arm: introduce symbol for ARM CPUsGeorges Savoundararadj2014-10-29-3/+0
| | | | | | | | | | | | | | | | | This commit introduces a Kconfig symbol for each ARM CPU: CPU_ARM720T, CPU_ARM920T, CPU_ARM926EJS, CPU_ARM946ES, CPU_ARM1136, CPU_ARM1176, CPU_V7, CPU_PXA, CPU_SA1100. Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected for CPU_ARM1176 and CPU_V7. For each target, the corresponding CPU is selected and the definition of SYS_CPU in the corresponding Kconfig file is removed. Also, it removes redundant "string" type in some Kconfig files.

* kconfig: remove redundant "string" type in arch and board KconfigsMasahiro Yamada2014-09-13-5/+0
| | | | | | | | | | | | | | | | | | Now the types of CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD, CONFIG_NAME} are specified in arch/Kconfig. We can delete the ones in arch and board Kconfig files. This commit can be easily reproduced by the following command: find . -name Kconfig -a ! -path ./arch/Kconfig | xargs sed -i -e ' /config[[:space:]]SYS_\(ARCH\|CPU\|SOC\|\VENDOR\|BOARD\|CONFIG_NAME\)/ { N s/\n[[:space:]]*string// } ' Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* Add board MAINTAINERS filesMasahiro Yamada2014-07-30-0/+6
| | | | | | | | | | | | | | | | | | | | We have switched to Kconfig and the boards.cfg file is going to be removed. We have to retrieve the board status and maintainers information from it. The MAINTAINERS format as in Linux Kernel would be nice because we can crib the scripts/get_maintainer.pl script. After some discussion, we chose to put a MAINTAINERS file under each board directory, not the top-level one because we want to collect relevant information for a board into a single place. TODO: Modify get_maintainer.pl to scan multiple MAINTAINERS files.

* kconfig: add board Kconfig and defconfig filesMasahiro Yamada2014-07-30-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | 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/.

* devkit3250: add Timll DevKit3250 board initial supportVladimir Zapolskiy2012-05-15-0/+109
This change adds a basic support for Embest/Timll DevKit3250 board, NOR and UART are the only supported peripherals for a moment. The board doesn't require low-level init, because the initial SDRAM and GPIO configuration is performed during kickstart bootloader execution.
