fda6fac39b dm: tegra: spi: Convert to driver model
This converts the Tegra SPI drivers to use driver model. This is tested
on:

- Tegra20 - trimslice
- Tegra30 - beaver
- Tegra124 - dalmore

(not tested on Tegra124)

783e6a72b8 kconfig: move CONFIG_OF_* to Kconfig
This commit moves:
  CONFIG_OF_CONTROL
  CONFIG_OF_SEPARATE
  CONFIG_OF_EMBED
  CONFIG_OF_HOSTFILE

Because these options are currently not supported for SPL,
the "Device Tree Control" menu does not appear in the SPL
configuration.

Note:
zynq-common.h should be adjusted so as not to change the
default value of CONFIG_SPL_FAT_LOAD_PAYLOAD_NAME.

Replace the custom $bootcmd with that from <config_distro_bootcmd.h>.
There should be no functional change, since the new generic $bootcmd was

fe7b7cd266 ARM: tegra: set initrd_high so boot scripts work
During bootm/z, U-Boot relocates the DTB and initrd to high memory so
they are out of the way of the kernel. On ARM at least, some parts of
high memory are "highmem" and can't be accessed at early boot. To solve
this, we need to restrict this relocation process to use lower parts of
RAM that area accessible.

For the DTB, an earlier patch of mine set CONFIG_SYS_BOOTMAPSZ. However,
since some platforms have different restrictions on DTB and initrd
location, that config option doesn't affect the initrd. We need to set
the initrd_high environment variable to control the initrd relocation.

Since we have carefully chosen the load addresses for the DTB and
initrd (see comments in include/configs/tegraNNN-common.h re: values in
MEM_LAYOUT_ENV_SETTINGS), we don't actually need any DTB or initrd
relocation at all. Skipping relocation removes some redundant work.
Hence, set both fdt_high and initrd_high to ffffffff which completely
disables relocation.

If the user does something unusual, such as using custom locations for
the DTB/initrd load address or wanting to use DTB/initrd relocation for
some reason, they can simply set these variables to custom values to
override these environment defaults.

With this change, cmd_sysboot works correctly for a filesystem created
by the Fedora installer.

4d7d2e570a ARM: tegra: rework boot scripts
Update the common Tegra boot scripts in the default environment to

a) Make use of the new "test -e" shell command to avoid some error
   messages.

b) Allow booting using the sysboot command and extlinux.conf. This
   allows easy creation of boot menus, and provides a simple interface
   for distros to parameterize/configure the boot process.

09266b270f ARM: tegra: clear $usb_need_init each boot
$usb_need_init prevents "usb start" from being run multiple times for
each boot attempt, i.e. once for USB storage, another for PXE, and
another for DHCP. However, the flag that's used to determine when to run
"usb start" is never cleared, so a subsequent "boot" command will never
probe for a freshly plugged in USB device. Fix this so that new USB
devices will be probed once per boot attempt.

b9b53a60ae ARM: tegra: set env vars to indicate Cardhu A04 support
The U-Boot "cardhu" build supports only revision 4 of the Cardhu board
and later compatible revisions. Hence, set $board_name in the default
environment to "cardhu-a04" rather than just "cardhu".

The Linux kernel has separate DTs for Cardhu A02 and A04, although the
former isn't really supported any more. Consequently, the kernel DT file
that matches the U-Boot cardhu build is "tegra30-cardhu-a04.dtb" rather
than "tegra30-cardhu.dtb". Set the $fdtfile default environment variable
to reflect this.

3786a942b5 tegra: use generic fs commands in BOOTCOMMAND
Modify tegra-common-post.h's BOOTCOMMAND definition to use the generic
filesystem command load rather than separate fatload and ext2load.
This removes the need to iterate over supported filesystem types in the
boot command.

This requires editing all board config headers to enable the new
commands. The now-unused commands are left enabled to assue backwards
compatibility with any user scripts. Boards (all from Avionic Design)
which define custom BOOTCOMMAND values are not affected.

938176a482 ARM: tegra: use standard variables to define load addresses
Currently, Tegra's default environment uses non-standard variables to define
where boot scripts should load the kernel, FDT, and initrd. This change both
changes the variable names to match those described in U-Boot's README, and
shuffles their values around a little so that the values make a little more
sense; see comments in the patch for rationale behind the values chosen.

Note that this patch does remove the old non-standard variable "fdt_load" from
the default environment, so this patch requires people to change their boot
scripts.

7f1b767aea ARM: tegra: define CONFIG_SYS_BOOTMAPSZ
This define indicates the size of the memory region where it is safe
to place data passed to the Linux kernel (ATAGs, DTB, initrd). The
value needs to be:

a) Less than or equal to RAM size.
b) Small enough that the area is not within the kernel's highmem region,
   since the kernel cannot access ATAGs/DTB/initrd from highmem.
c) Large enough to hold the kernel+DTB+initrd.

256M seems large enough for (c) in most circumstances, and small enough
to satisfy (a) and (b) across any possible Tegra board. Note that the
user can override this value via environment variable "bootm_mapsize"
if needed.

The advantage of defining BOOTMAPSZ is that we no longer need to define
variable fdt_high in the default environment. Previously, we defined
this to prevent the DTB from being relocated to the very end of RAM,
which on most Tegra systems is within highmem, and hence which would
cause boot failures. A user can still define this variable themselves
if they want the FDT to be either left in-place wherever loaded, or
copied to some other specific location. Similarly, there should no
longer be a strict requirement for the user to define initrd_high if
using an initrd.
