Subject: stm32mp: stm32prog: support empty flashlayout
X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=4d7df7f7666a2bc6b0b8980969b69c8008b90af6;p=u-boot.git

stm32mp: stm32prog: support empty flashlayout

When the STM32CubeProgrammer sent a empty flashlayout.tsv
file, the command stm32prog correctly parse the file
but data->dev_nb = 0 and the stm32prog_devices_init
operations should be skipped.
