[U-Boot] Remove STM32F1 support ?

Hi Matt, Kamil

I currently doing some work on STM32 SoCs on U-boot, more precisely code factorization between STYM32F4, STM32F7 and STM32H7

I noticed you added STM32F1 SoCs support few years ago :

0144caf22ce6acd5c gpio: stm32: add stm32f1 support 2d18ef2364fd3561a ARMv7M: add STM32F1 support

But neither STM32F1 dedicated defconfig nor board was associated to these commits.

In order to facilitate the cleaning work i am currently doing, can i removed STM32F1 support ? (ie all files located in arch/arm/mach-stm32/stm32f1 and in arch/arm/include/asm/arch-stm32f1)

Regards

Patrice
