tiny-printf: Add support for %p format Add support for %p, %pa[p], %pM, %pm and %pI4 formats to tiny-printf. %pM and %pI4 are widely used by SPL networking stack and is required if networking support is desired in SPL. %p, %pa and %pap are mostly used by debug prints and hence supported only when DEBUG is enabled. Before this patch: $ size spl/u-boot-spl text data bss dec hex filename 99325 4899 218584 322808 4ecf8 spl/u-boot-spl After this patch (with CONFIG_SPL_NET_SUPPORT): $ size spl/u-boot-spl text data bss dec hex filename 99666 4899 218584 323149 4ee4d spl/u-boot-spl So, this patch adds ~350 bytes to code size. If CONFIG_SPL_NET_SUPPORT is not enabled, this adds ~25 bytes. If CONFIG_USE_TINY_PRINTF is disabled then: $ size spl/u-boot-spl text data bss dec hex filename 101116 4899 218584 324599 4f3f7 spl/u-boot-spl So, there is still ~1.4K space saved even with support for %pM/%pI4. Compiler used is to build is: arm-linux-gnueabihf-gcc (Linaro GCC 6.2-2016.11) 6.2.1 20161016 Signed-off-by: Vignesh R <vigneshr@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com> Reviewed-by: Simon Glass <sjg@chromium.org>
