In barebox we have an option for dynamic formation of the CRC32
table (DYNAMIC_CRC_TABLE), but the source code declares a static
array which is simply filled with data, the resulting code becomes
even more than without DYNAMIC_CRC_TABLE option, due to the BSS usage.
CONFIG_DYNAMIC_CRC_TABLE=n
text data bss dec hex filename
1884 0 0 1884 75c crc32.o
CONFIG_DYNAMIC_CRC_TABLE=y
text data bss dec hex filename
1066 4 1024 2094 82e crc32.o
This patch provides dynamic buffer allocation for the CRC table,
which saves about 1 Kbyte, as it should be.
CONFIG_DYNAMIC_CRC_TABLE=y
text data bss dec hex filename
1062 0 4 1066 42a crc32.o
