Currently the bmode "usb" uses BOOT_CFG1 to 0x01, -which means
BOOT_CFG1[7:4] is set to b0000. According to Table 8-7 Boot
Device Selection this is NOR/OneNAND and not Reserved.
Use 0x10 which leads to b0001, which is a Reserved boot device.
With that the SoC reliably falls back to the serial loader.

2. We think 48MHz is fast enough for pmu pclk and it is lower power cost
than 99MHz,
3. PPLL 676 MHz and PMU_PCLK 48MHz are the clock rate we are using

relocated, such as do_fat_read_at_block. Once eMMC controller transfer

Given that boot monitor image is being generated to a specific target location
depending on the SoC and U-boot relies on addr_mon env variable to be aligned
with boot monitor target location. When ever the target address gets updated in
boot monitor, it is difficult to sync between u-boot and boot monitor and also
there is no way to update user that boot monitor image is updated.
To avoid this problem, boot monitor image is being generated with mkimage
header. Adding support in mon_install command for parsing this header.

Commit ce02a71c23 "tegra: dts: Sync tegra20 device tree files with
Linux" enabled the ULPI USB port on Ventana, but made no attempt to ensure
that U-Boot code could handle this. In practice, various code is missing,
and various configuration options are not enabled, which causes U-Boot to
hang when attempting to initialize this USB port. This patch enables ULPI
PHY support on Ventana, and adds the required pinmux setup for the port to
operate. Note that Ventana is so similar to Seaboard that this change is
made in the Seaboard board file, which is shared with Ventana.
Seaboard also has the ULPI USB port wired up in hardware, although to an
internal port that often doesn't have anything attached to it. However,
the DT nodes for the USB controller and PHY had different status property
values, so the port was not initialized by U-Boot. Fix this inconsistency,
and enable the ULPI port, just like in the Linux kernel DT. This likewise
requires enabling ULPI support in the Seaboard defconfig.
