2021-07-15lib/vsprintf.c: remove unused ip6_addr_string()Rasmus Villemoes
There's currently no user of %p[iI]6, so including ip6_addr_string() in the image is a waste of bytes. It's easy enough to have the compiler elide it without removing the code completely. The closest I can find to anybody "handling" ipv6 in U-Boot currently is in efi_net.c which does if (ipv6) { ret = EFI_UNSUPPORTED; As indicated in the comment, it can easily be put back, but preferably under a config knob.

Copy these from Linux v5.7-rc5 tag. This brings in some handy new attributes and is otherwise important to keep in sync. We drop the reference to smp_read_barrier_depends() as it is not relevant on the architectures we support at this time, based on where it's implemented in Linux today.

2019-06-07lib/vsprintf: allow printing upper case GUIDsHeinrich Schuchardt
In the UEFI context GUIDs are expected to be rendered in upper case. The patch uses the formerly unused bit 1 of the parameter str_format of function uuid_bin_to_str() to indicate if we need upper or lower case output. Function uuid_string() in vsprint.c is adjusted to correctly set the bit depending on the print format code. %pUb: 01020304-0506-0708-090a-0b0c0d0e0f10 %pUB: 01020304-0506-0708-090A-0B0C0D0E0F10 %pUl: 04030201-0605-0807-090a-0b0c0d0e0f10 %pUL: 04030201-0605-0807-090A-0B0C0D0E0F10 Up to this point only a diagnostic message in mount_ubifs() using '%pUB' is concerned by the change.

2019-04-11vsprintf: Support phys_addr_t specifier unconditionallyThierry Reding
When phys_addr_t printf specifier support was first introduced in commit 1eebd14b7902 ("vsprintf: Add modifier for phys_addr_t"), it was enabled only if CONFIG_CMD_NET was selected.

2015-11-23lib/tiny-printf.c: Add tiny printf function for space limited environmentsStefan Roese
This patch adds a small printf() version that supports all basic formats. Its intented to be used in U-Boot SPL versions on platforms with very limited internal RAM sizes. To enable it, just define CONFIG_USE_TINY_PRINTF in your defconfig. This will result in the SPL using this tiny function and the main U-Boot still using the full-blown printf() function. This code was copied from: http://www.sparetimelabs.com/printfrevisited With mostly only coding style related changes so that its checkpatch clean. The size reduction is about 2.5KiB. Here a comparison for the db-mv784mp-gp (Marvell AXP) SPL: Without this patch: 58963 18536 1928 79427 13643 ./spl/u-boot-spl With this patch: 56542 18536 1956 77034 12cea ./spl/u-boot-spl Note: To make it possible to compile tiny-printf.c instead of vsprintf.c when CONFIG_USE_TINY_PRINTF is defined, the functions printf() and vprintf() are moved from common/console.c into vsprintf.c in this patch.
