[Buildroot] [PATCH v2 1/4] configs: atmel: unify and update defconfig for Xplained boards

[Ludovic Desroches]

Unify and update the defconfig files for Atmel Xplained boards:
- use at91bootstrap as first stage bootloader instead of u-boot spl
- build all dtb variants
- bump to linux4sam_5.2

[Buildroot] [PATCH v2 4/4] board/atmel: merge and update documentation

[Ludovic Desroches]

There were two readme files (one for flashing on NAND and one to create a
SD card) in different places. Merge them and update the SD card
generation part since all Xplained boards are supported and the -u
option of sfdisk is obsolete on latest versions.

 Configuring and building Buildroot
-----------------------------------
+==================================
+
+For Xplained boards, an alternative mmc defconfig file is provided to boot from
+an SD card: first stage bootloader, second stage bootloader, kernel image,
+device tree file and root file system are all located on the SD card.
 
   make <board>_defconfig
   make
 
+goto to 'Flashing the NAND using SAM-BA' section
+
+or
+
+  make <board>_mmc_defconfig
+  make
+
+goto to 'Preparing the SD card' section
+
+
+Preparing the SD card
+=====================
+
+The SD card must be partitioned with at least two partitions: one
+FAT16 partition for the bootloaders, kernel image and Device Tree
+blob, and one ext4 partition for the root filesystem. To partition the
+SD card:
+
+sudo sfdisk /dev/mmcblk0 <<EOF
+,64MiB,6
+;
+EOF
+
+This creates a 64 MB partition for the FAT16 filesystem (type 6) and
+uses the rest for the ext4 filesystem used for the root filesystem.
+
+Then, format both partitions:
+
+sudo mkfs.msdos -n boot /dev/mmcblk0p1
+sudo mkfs.ext4 -L rootfs -O ^huge_file /dev/mmcblk0p2
+
+ Note: the -O ^huge_file option is needed to avoid enabling the huge
+ files features of ext4 (to support files larges than 2 TB), which
+ needs the kernel option CONFIG_LBDAF to be enabled.
+
+Mount both partitions (if not done automatically by your system):
+
+sudo mount /dev/mmcblk0p1 /media/boot
+sudo mount /dev/mmcblk0p2 /media/rootfs
+
+Copy the bootloaders, kernel image and Device Tree blob to the first
+partition:
+
+cp output/images/boot.bin /media/boot/
+cp output/images/u-boot.bin /media/boot/
+cp output/images/zImage /media/boot/
+cp output/images/at91-sama5d2_xplained.dtb /media/boot/
+
+Extract the root filesystem to the second partition:
+
+sudo tar -C /media/rootfs -xf output/images/rootfs.tar
+
+Unmount both partitions:
+
+sudo umount /media/boot
+sudo umount /media/rootfs
+
+Insert your SD card in your Xplained board, and enjoy. The default
+U-Boot environment will properly load the kernel and Device Tree blob
+from the first partition of the SD card, so everything works
+automatically.

host-samba is not needed/useful for SD card configurations, so I've
dropped this last line and applied. Thanks!

I've slightly tweaked the explanation about NAND flash vs. SD card
configurations, and moved the SD card discussion after the NAND flash
discussion. Then I've applied.
