2 This is a board-level BSP directory.
4 The code here needs to cover these aspects:
6 + Type and mapping for Flash memories, and how they are partitioned.
7 + Tie-up with the boot-loader, e.g. u-Boot vs. CFE loader interface.
8 + The means to access and share NVRAM or environment settings with th eloader.
9 + The frequency of the oscilator or crystal, unless the SoC has
10 straps allowing automatic detection of that frequency.
11 + The assignments of multi-function I/O pins on the SoC.
12 + Any ICs that are external to the main SoC that are not handler
13 by auto-detecting (such as PCI/PCIe connected peripherals),
14 including those connected with I2C.
15 + Any other aspect of the SoC that can differ in board-level implementation.
17 All other aspects of the BSP are handled in the Platform directory.
