The SDHCI driver assigns dynamic device numbers (mmcblk0/1/...) to
devices based on when they get probed, which IDs are free at that time,
etc. Many boards have e.g. 1 fixed MMC soldered onto the board, and 1
SD slot. There may or may not be a card in the SD slot at probe time,
which can then cause
tegra250.dts describes everything within the Tegra SoC, but leaves all
optional devices disabled.
tegra-harmony.dts is now the configuration of the SoC for the board,
i.e. it enables the optional devices that are required for the board,
and provides any required platform data for those devics.

Yeah. You want that now for testing? Or just with the release?

If a dtb is passed to the kernel then the kernel needs to iterate
through compiled-in mdescs looking for one that matches and move the
dtb data to a safe location before it gets accidentally overwritten by
the kernel.
This patch creates a new function, setup_machine_fdt() which is
analogous to the
In preparation for adding device tree support, this patch consolidates
all of the atag-specific setup into a single function.
v5: - drop double printk("Machine; %s\n", ...); call.
- leave copying boot_command_line in setup_arch() since it isn't
atags specific.
v4: - adapt to the removal
Add some basic empty infrastructure for DT support on ARM.
v5: - Fix off-by-one error in size calculation of initrd
- Stop mucking with cmd_line, and load command line from dt into
boot_command_line instead which matches the behaviour of ATAGS booting
v3: - moved cmd_line export and init
The dtb is passed to the kernel via register r2, which is the same
method that is used to pass an atags pointer. This patch modifies
__vet_atags to not clear r2 when it encounters a dtb image.
