[U-Boot] [PATCH v6 00/10] armv8: ls2080aqds: Enable QSPI boot support

[Yuan Yao]

From: Yuan Yao <yao.yuan@nxp.com>

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.

[U-Boot] [PATCH v6 04/10] armv8: ls2080aqds: disable IFC NOR & QIXIS when QSPI enable

[Yuan Yao]

From: Yuan Yao <yao.yuan@nxp.com>

When QSPI is enabled, NOR flash and QIXIS can't be accessed
through IFC due to pin mux.
So enable I2C QIXIS access and I2C early init to read the
sysclk and ddrclk.

Signed-off-by: Yuan Yao <yao.yuan@nxp.com>
---
Changed in v5:
	Use I2C to read the clocks instead of the hard-coded clocks.

[U-Boot] [PATCH v6 08/10] configs: ls2080a: Increase load image len in NAND boot

[Yuan Yao]

From: Yuan Yao <yao.yuan@nxp.com>

Freescale QSPI and DSPI driver have been converted to Driver Mode.
This converting bring dtb file for u-boot and this increase the size
of u-boot image.
LS2080A nand boot use SPL framework.
This patch increase the size of image load from NAND to RAM in SPL.

[U-Boot] [PATCH v6 10/10] armv8: ls2080aqds: Enable QSPI boot support

[Yuan Yao]

From: Yuan Yao <yao.yuan@nxp.com>

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.

Changed in v6:
	Add CONFIG_CMD_SF in defconfig.
Changed in v4:
	Merged the below patch into one:
	board: freescale: ls2080aqds: Enable early I2C access for QSPI boot
Changed in v3:
	1, Rebase to lastest code.
	2, Give up to change the sequence for "show_board_info" in "init_sequence_f".
