[U-Boot] [PATCH v8 24/28] armv8/ls2085aqds: NAND boot support

[U-Boot] [PATCH v8 24/28] armv8/ls2085aqds: NAND boot support

[York Sun]

From: Scott Wood <scottwood@freescale.com>

This adds NAND boot support for LS2085AQDS, using SPL framework.
Details of forming NAND image can be found in README.

Signed-off-by: Scott Wood <scottwood@freescale.com>
Signed-off-by: York Sun <yorksun@freescale.com>

---

Changes in v8:
  Update README to match the example for QDS NAND boot.

Changes in v7:
  Move NAND boot instruction to fsl-lsch3/README.
  Update board setting to put RCW and u-boot in different NAND block.

Changes in v6: None
Changes in v5:
  Update LS2085AQDS README to include instructions to form NAND image

Changes in v4:
  Update MAINTAINERS file

Changes in v3: None
Changes in v2: None

+Booting from NAND
+-------------------
+Booting from NAND requires two images, RCW and u-boot-with-spl.bin.
+The difference between NAND boot RCW image and NOR boot image is the PBI
+command sequence. Below is one example for PBI commands for QDS.
+
+1) CCSR 4-byte write to 0x00e00404, data=0x00000000
+2) CCSR 4-byte write to 0x00e00400, data=0x1800a000
+The above two commands set bootloc register to 0x00000000_1800a000 where
+the u-boot code will be running in OCRAM.
+
+3) Block Copy: SRC=0x0107, SRC_ADDR=0x00100000, DEST_ADDR=0x1800a000,
+BLOCK_SIZE=0x00014000
+This command copies u-boot image from NAND device into OCRAM. The values need
+to adjust accordingly.
+
+SRC		should match the cfg_rcw_src, the reset config pins. It depends
+		on the NAND device. See reference manual for cfg_rcw_src.
+SRC_ADDR	is the offset of u-boot image in NAND device. It should match
+		CONFIG_SYS_NAND_U_BOOT_OFFS. In the example above, it is 1MB.
+DEST_ADDR	is fixed at 0x1800a000, matching bootloc set above.
+BLOCK_SIZE	is the size to be copied by PBI.
+
+RCW image should be written to the beginning of NAND device. Example of using
+u-boot command
+
+nand write <rcw image in memory> 0 <size of rcw image>
+
+To form the NAND image, build u-boot with NAND config, for example,
+ls2085aqds_nand_defconfig. The image needed is u-boot-with-spl.bin.
+
+The u-boot image should be written to the offset CONFIG_SYS_NAND_U_BOOT_OFFS,
+in above example 0x100000.
+
+nand write <u-boot image in memory> 100000 <size of u-boot image>
+
+With these two images in NAND device, the board can boot from NAND.

[U-Boot] [PATCH v8 26/28] armv8/ls2085ardb: Enable NAND SPL support

[York Sun]

From: Scott Wood <scottwood@freescale.com>

Enable NAND boot support using SPL framework. To boot from
NAND, either use DIP switches on board, or "qixis_reset nand"
command. Details of forming NAND image can be found in README.

Signed-off-by: Scott Wood <scottwood@freescale.com>
Signed-off-by: York Sun <yorksun@freescale.com>

---

Changes in v8:
  Update README to add example for RDB NAND boot.

Changes in v7:
  Move NAND boot instruction to fsl-lsch3/README.
  Update board setting to put RCW and u-boot in different NAND block.

Changes in v6: None
Changes in v5:
  Fix signed-off-by signature
  Update LS2085ARDB README to include instructions to form NAND image

Changes in v4:
  Update MAINTAINERS file

Changes in v3: None
Changes in v2: None

Why 1 MiB?

I got it wrong. I though the erase size is 1MB, but actually it is 128KB. I will
fix it.
