Subject: configs: stm32mp1: Add support for baudrates higher than 115200 for st-link
X-Git-Url: http://git.dujemihanovic.xyz/img/static/gitweb.css?a=commitdiff_plain;h=5367b67be4a3d26197fe5bf7baef2bf125997047;p=u-boot.git

configs: stm32mp1: Add support for baudrates higher than 115200 for st-link

On STMicroelectronics boards, the UART can reliably go up to
2000000 bauds when connected to the on-board ST-LINK-V2 for STM32MP15

Unfortunately U-Boot will fall back to 115200 unless higher rates are
declared via CONFIG_SYS_BAUDRATE_TABLE.

This patch add the support of higher baudrates on STMicroelectronics
boards with ST-LINK.
