arm, keymile: updates for the arm based boards from keymile
define KM_IVM_BUS and KM_ENV_BUS macros KM_IVM_BUS is used to define the EEprom_ivm environment variable. These macros allow the reuse of these I2C addresses in other code locations. remove unneeded code On first HW versions the BOCO FPGA was behind a MUX device. These HW versions are not supported anymore. And therefore this code can be removed. added LED initialization for SUEN3 The bootstat LED required to be initialized so to have a green colour after start-up. define CONFIG_SYS_TEXT_BASE This is needed by the relocation code and is not the same for our ARM BEC and thus needs to be defined. remove memsize variable An environment variable for memsize is not needed. this can be get via the board info struct. remove unneeded double access to bi_dram[i].size field Signed-off-by: Valentin Longchamp <valentin.longchamp@keymile.com> Signed-off-by: Holger Brunck <holger.brunck@keymile.com> Signed-off-by: Luca Haab <luca.haab@keymile.com> Signed-off-by: Heiko Schocher <hs@denx.de> cc: Prafulla Wadaskar <prafulla@marvell.com>
