X-BeenThere: u-boot@lists.denx.de X-Mailman-Version: 2.1.11 Precedence: list List-Id: U-Boot discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: u-boot-bounces@lists.denx.de Errors-To: u-boot-bounces@lists.denx.de This adds support for the AT91SAM9G20 boards by taskit GmbH. Both boards, Stamp9G20 and PortuxG20, are integrated in one file. PortuxG20 is basically a SBC built around the Stamp9G20. Signed-off-by: Markus Hubig Cc: Andreas Bießmann --- Changes for v2: - Added myself to the MAINTAINERS file. - Fixed a missleading comments. - Removed "Enable EMAC clock". - Enabled the at91sam9 hw watchdog. - Adding a timeout to PHY reset. - Uses the generic CONFIG_MACH_TYPE in stamp9g20.h. - Removed "mem=64M" from basicargs, its set by ATAGS. - Increased the space for the linux kernel to 6Mb. - Removed the "#ifdef CONFIG_MACB" switches. - Removed all tailing whitespaces in comments. - Removed CONFIG_USART3 its not used any more. - CONFIG_SYS_BAUDRATE_TABLE is now generic. - Removed the nowhere referenced CONFIG_STACKSIZE. - Removed the unessasary IRQ stuff. - Removed CONFIG_RESET_PHY_R & reset_phy(). Changes for v3: - Moved all board specifig stuff into one block. - Fixed error in boards.cfg. - Added some comments about the PC5 and PC9 pins. - Making networking support configurable again. - Added autoload and autoboot to EXTRA_ENV_SETTINGS. - Fixed some minor issues with the timeout function. - Enabled CONFIG_CMD_SOURCE again. Changes for v4: - Fixed some trailing whitespace style errors. - Enabled the STATUS_LED framework. - Fixed the URSTEN handling while PHY reset. Changes for v5: - Enables the PIOA clock in coloured_LED_init. - Fixes some typos. - Fixes some 'parentheses' compiler warnings. - Unifies the calculations to use shifting '<<'. - Removes the obsolete CONFIG_ARCH_CPU_INIT. - Removes unused variable. - Fixes MAINTAINERS manipulation.
