For lulz, added a (commented out) dma-from-SRAM2 option, and gltching still occurs; the problem is twofols .. hitting SRAM1 during DMA, or hitting GPIO during DMA, will glitch. Use FSMC memory controller or USART/I2C to talk to other chips, as they are on other buses.. and feed them into SRAM2 fia DMA1, say. FSMC to mount the Z80 RAM may be most awesome...
