-Subject: [PATCH 1/8] mmc: meson-gx: limit segments to 1 when dram-access-quirk
- is needed
-
-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 functionnality with the brcmfmac/bcmsdh driver on Amlogic
-G12A/G12B SoCs on boards like SEI510 or Khadas VIM3.
