This area of memory will be + typically located right below the malloc() area and mapped + uncached in the MMU. This is useful for drivers that would + otherwise require a lot of explicit cache maintenance. For + some drivers it's also impossible to properly maintain the + cache.

This can + happen for example in network drivers where descriptors for + buffers are typically smaller than the CPU cache-line (e.g. + 16 bytes vs. 32 or 64 bytes). + + Non-cached memory is only supported on 32-bit ARM at present. + - CONFIG_SYS_BOOTM_LEN: Normally compressed uImages are limited to an uncompressed size of 8 MBytes.
