Flash layout file changes for Tegra210 platforms

NVIDIA has updated their flashing tools in the Tegra210 BSP package so the id= field in the flash layout XML file is used as the partition number in the GPT of the eMMC/SDcard. They have updated their flash layouts to reflect that, with the APP partition appearing at the end of the file with id="1". Bear this in mind if you have customized flash layouts for your TX1 or Nano devices.

Kernel recipe using new branch

The kernel update into the patches-l4t-r32.4 branch did not merge cleanly, so a the linux-tegra_4.9.bb recipe now points to a new oe4t-patches-l4t-r32.4 branch which has our patches rebased on top of the R32.4.4 release from NVIDIA.

JetPack updates

None of the JetPack packages have changed in 4.4.1, except for a minor update to the Tegra MultiMedia API SDK. The update obsoletes a patch for an issue that was present in the R32.4.3/4.4 version of the SDK.

SDK Manager no longer required

As of 24 Apr 2021, the host-side (x86-64) CUDA recipes have been updated to use package feeds that NVIDIA has added for them as well. SDK Manager is no longer required.
