#     mtd: spi-nor: aspeed: Add read training support for the AST2600
#     
#     The read training algorithm consists of finding the appropriate read
#     timing delays for the HCLK dividers in range [ 2 - 5 ] and store the
#     results in the Read Timing Compensation register. The previous AST2500
#     and AST2400 SoCs were covering a broader HCLK range [ 1 - 5 ] because
#     the AHB frequency was lower.
#     
#     The algorithm first reads a golden buffer at low speed and then
#     performs reads with different clocks and delay cycle settings to find
#     a breaking point. This selects the default clock frequency for the CEx
#     control register. The current settings are bit optimistic as we pick
#     the first delay giving good results. A safer approach would be to
#     determine an interval and choose the middle value. We might change the
#     approach depending on the results on other systems.

WARNING: vmlinux.o(.text.unlikely+0x328): Section mismatch in reference from the function free_memmap() to the function .meminit.text:memblock_free()
The function free_memmap() references
the function __meminit memblock_free().
This is often because free_memmap lacks a __meminit 
annotation or the annotation of memblock_free is wrong.
