-Subject: [PATCH] introduce-BANKCON-meddling-sysfs.patch
-
-A few questions have been flying around about how optimal
-our waitstates are for various things including Glamo.
-
-This patch introduces new sysfs nodes
-
-/sys/devices/platform/neo1973-memconfig.0/BANKCON0
-...
-/sys/devices/platform/neo1973-memconfig.0/BANKCON7
-
-If you cat them you get translated info about bus speed on
-that chip select, eg,
-
-# cat /sys/devices/platform/neo1973-memconfig.0/BANKCON1
-BANKCON1 = 0x00000A40
- Type = ROM / SRAM
- PMC  = normal (1 data)
- Tacp = 2 clocks
- Tcah = 0 clocks
- Tcoh = 1 clock
- Tacc = 3 clocks
- Tcos = 1 clock
- Tacs = 0 clocks
-
-You can write them in hex too
-
-# echo 0x200 > /sys/devices/platform/neo1973-memconfig.0/BANKCON1
-
-The write format for BANKCON0 - 5 looks like this
-
- b1..b0   PMC  Page Mode Config
- b3..b2   Tacp Page Mode Access Cycle
- b5..b4   Tcah Address hold after CS deasserted
- b7..b6   Tcoh CS hold after OE deasserted
- b10..b8  Tacc Access Cycle Period
- b12..b11 Tcos CS setup before OE asserted
- b14..b13 Tacs Address setup before CS asserted
-
-BANKCON 6 and 7 have two extra bits
-
- b16..b15  MT  Memory type (00=ROM/SRAM, 11=DRAM)
-
-If it's ROM/SRAM, the rest of the bits are as described above.
-For DRAM
-
- b1..b0   SCAN Column address number
- b3..b2   RAS to CAS delay
-
-The patch is intended to let people experiement on their own.  But
-of course you will crash things for sure if the timing is wrong, and
-you can also trash SD Card data if you make Glamo unstable, so remove
-it or remount ro first.  Other horrible things are possible, but
-because the settings aren't sticky, you should always be able to
-recover by either normal reboot usually or at worst NOR boot and then
-dfu.  Most likely you will just crash your session and have to reboot
-if your settings are bad, but consider yourself warned bad things are
-possible. :-)
