[U-Boot-Users] [PATCH] OMAP242x/H4 board updates.
Hello,
This patch is against a CVS pull from today (3Mar05). It updates the H4 board for operation with the OMAP242x ES2 chip. Along with some other fixes it also switches to using the CFI flash driver for a 6x write speed up.
The CFI driver needed some minor changes as this Intel part works on a per partition basis. The current driver would assume that a query command to the base of the part would affect the whole chip. This is not the case. It also had some strange code which acted like sector unlocks were per chip instead of per sector, this is not the case.
- OMAP242x H4 board update - fix for ES2 differences. - switch to using the cfi_flash driver. - fix SRAM build address. - fix for GP device operation. - unlock SRAM for GP devices. - display more device information. - fix potential deadlock in omap24xx_i2c driver. - fix DLL load values to match dpllout*1 operation. - fix 2nd chip select init for combo DDR device. - cfi_flash.c - add support for CFI Intel 28F256L18 on H4 board.
Regards, Richard W.

Thanx Richard. I have received the custom board (I codenamed it 'tsunami'), but it is with hardware guys to do initial testing, I will soon get it on my desk.
- unlock SRAM for GP devices.
AFAIK, GP devices are configured at chip level, means, it depends on what chip I had received. _or_ will it be possible to to configure EVM for to access full SRAM?
As per our obeservations codecs like software had significant performance running in IVA when access to SDRAM from ARM11 is less...meaning let's put part of continously running Linux code in SRAM and reduce SDRAM contention.

Added, except for CFI driver changes which affect other boards as well.
The CFI driver needed some minor changes as this Intel part works on a per partition basis. The current driver would assume that a query command to the base of the part would affect the whole chip. This is not the case. It also had some strange code which acted like sector unlocks were per chip instead of per sector, this is not the case.
Please let's handle the CFI driver updates separately - see previous discussion about this.
Best regards,
