The actual max_segs computation leads to failure while using the broadcom sdio brcmfmac/bcmsdh driver, since the driver tries to make usage of scatter gather. But with the dram-access-quirk we use a 1,5K SRAM bounce buffer, and the max_segs current value of 3 leads to max transfers to 4,5k, which doesn't work. This patch sets max_segs to 1 to better describe the hardware limitation, and fix the SDIO functionality with the brcmfmac/bcmsdh driver on Amlogic G12A/G12B SoCs on boards like SEI510 or Khadas VIM3.
