Hmm it turns out my compiler is d.r.t as far as it is concerned: # 34 "/usr/lib/gcc/arm-none-eabi/5.4.1/include/stdint-gcc.h" 3 4 typedef signed char int8_t; typedef short int int16_t; typedef long int int32_t; typedef long long int int64_t; typedef unsigned char uint8_t; typedef short unsigned int uint16_t; typedef long unsigned int uint32_t; -- Alex Bennée

So we can have portable formatting of uint32_t types. Signed-off-by: Alex Bennée <alex.bennee@linaro.org> --- lib/libcflat.h | 5 +++++ 1 file changed, 5 insertions(+)
