[U-Boot] [PATCH v3 00/11] 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.

Yuan Yao (11):
  armv8: ls2080aqds: Select QSPI CLK div via SCFG
  configs: ls2080a_common: Remove duplicate NOR configs
  configs: ls2080aqds: disable IFC NOR & QIXIS when QSPI enable
  configs: ls2080aqds: Enable QSPI flash support
  dm: dts: ls2080aqds: Add QSPI dts node
  armv8: ls2080aqds: Config QSPI pin mux via FPGA in NAND boot
  configs: ls2080a: Increase load image len in NAND boot
  ls2080aqds_nand_defconfig: Enable QSPI & its dependence
  armv8: ls2080aqds: Enable QSPI boot support
	Rebase in v3.
  drivers: i2c: mxc: Add early init
	New add in v3.
  board: freescale: ls2080aqds: Enable early I2C access for QSPI boot
  	New add in v3.

[U-Boot] [PATCH v3 07/11] 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 v3 11/11] board: freescale: ls2080aqds: Enable early I2C access for QSPI boot

[Yuan Yao]

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

When QSPI boot is used, board FPGA is not accessible from IFC.
To use I2C interface instead, i2c needs to be initialized before knowing
the exact clock rate.

Yuan,

Do you think you can reorder these patches so that early i2c init can be in
front of disabling IFC? Then you don't have to use fixed clk at all. I am
thinking if we run git bisect and this set could break QSPI boot if sys clk is
other than 100MHz.

Sorry for the mistake, it's a good suggestion.
I will resend the patch soon.
Thanks for your review.
