SPL: tiny-printf: add "l" modifier
tiny-printf does not know about the "l" modifier so far, which breaks
the crash dump on AArch64, because it uses %lx to print the registers.
Add an easy way of handling longs correctly.
Using a relatively decent compiler (GCC 5.3.0) this does _not_ increase
the code size of tiny-printf.o for 32-bit builds (where long and int
are actually the same), actually it looses three (ARM Thumb2) instructions
from the actual SPL (numbers for orangepi_plus_defconfig):
text data bss dec hex filename
758 0 0 758 2f6 spl/lib/tiny-printf.o before
18839 488 232 19559 4c67 spl/u-boot-spl before
758 0 0 758 2f6 spl/lib/tiny-printf.o after
18833 488 232 19553 4c61 spl/u-boot-spl after
This adds some substantial amount of code to a 64-bit build, though:
(taken after a later commit, which enables the ARM64 SPL build for sunxi)
text data bss dec hex filename
1542 0 0 1542 606 spl/lib/tiny-printf.o before
25830 392 360 26582 67d6 spl/u-boot-spl before
1758 0 0 1758 6de spl/lib/tiny-printf.o after
26040 392 360 26792 68a8 spl/u-boot-spl after
