2010-03-31	0b54f2c Browse files » nand_imx: clear INT_MSK to fix i.MX21 nand boot ... For some weird reason this fixes nand boot on i.MX21. Since interrupts are globally disabled it doesn't hurt on other SoCs. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 31 Mar 2010
2010-03-30	d038318 Browse files » imx_nand: use memcpy for copying from/to buffer ... We do not need to use memcpy32 in read_buf/write_buf because in these functions we only access SDRAM and not the internal SRAM buffer.

	d5578b8 Browse files » nand_imx: Speed up sequential read ... When reading a page from nand prefetch the next page afterwards to keep the controller busy. This way we can improve sequential reading from NAND which is the common case for barebox. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 30 Mar 2010
	9d9be6b Browse files » nand_imx: use optimized memcpy ... The internal SRAM buffer of the i.MX NAND controller does not allow byte accesses. We use the memcpy32 function to handle this. If we have assembler optimized string functions we can do better because they won't do byte accesses when source and target are word aligned.

2010-01-29	512a1c8 Browse files » Fix nand_imx for i.MX21 ... Recent changes to the nand_imx driver broke it for i.MX21 systems; the i.MX21 NAND controller is more akin to the one in i.MX27/i.MX31, than to the one in i.MX25/i.MX35.
