[U-Boot] [PATCH v2 0/6] Add ARMv7M STM32F1 and STM3210E-EVAL board support

This series adds support for the STM32F1 SoC family and the STM3210E-EVAL
board on top of the STM32F4 SoC family support [1].

Since this board has no DRAM the first patch fixes the build when
CONFIG_NR_DRAM_BANKS is not set. A patch is also required to force the
processor to stay in Thumb mode when 'go'ing to an application.

As the STM32F1 differs greatly from STM32F4 in flash and clock layout,
there's a separate subdirectory for the STM32F1 family. The gpio and
serial drivers are shared as these peripherals are mostly similar with
only the pinmux bits being significantly different in the gpio driver.

The STM3210E-EVAL board is supported with 1MiB Flash and 96KiB of SRAM
on the STM32F103ZGT6, USART1 for console, and four user LEDs.
