This patch adds QSPI boot support for LS2080AQDS board. The QSPI boot image need to be programmed into the QSPI flash first. Then we can switch to booting from QSPI memory space.
Signed-off-by: Yuan Yao yao.yuan@nxp.com --- Changed in v3: 1, Rebase to lastest code. 2, Give up to change the sequence for "show_board_info" in "init_sequence_f". Changed in v4: Merged the below patch into one: board: freescale: ls2080aqds: Enable early I2C access for QSPI boot --- arch/arm/include/asm/arch-fsl-layerscape/cpu.h | 4 ++++ board/freescale/ls2080aqds/ls2080aqds.c | 5 +++++ configs/ls2080aqds_qspi_defconfig | 27 ++++++++++++++++++++++++++ include/configs/ls2080a_common.h | 2 ++ include/configs/ls2080aqds.h | 18 +++++++++++++---- 5 files changed, 52 insertions(+), 4 deletions(-) create mode 100644 configs/ls2080aqds_qspi_defconfig
