Hi Jagan and Tom,
Any chance to get this patch series into the u-boot? I haven't heard any feedback and comments but they are largely based on patch series for linux that was accepted in kernel stable release 6.3 and verified on Broadcom reference boards.
Thanks, William

This patch series is the u-boot port from the recently accepted kernel Broadcom HSSPI driver patch series here [1]. It includes the accumulative updates and fixes for the driver from Broadcom. It also added a new driver for the updated SPI controller found in the new BCMBCA SoC. The device tree document is converted to yaml format and updated accordingly.
Changes in v2:
- Add Álvaro Fernández Rojas as another maintainer
