| * mtd: nand: rename NAND_USE_FLASH_BBTBrian Norris2011-09-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recall the recently added prefix requirements: * "NAND_" for flags in nand.h, used in nand_chip.options * "NAND_BBT_" for flags in bbm.h, used in nand_chip.bbt_options or in nand_bbt_descr.options Thus, I am changing NAND_USE_FLASH_BBT to NAND_BBT_USE_FLASH. Again, this flag is found in bbm.h and so should NOT be used in the "nand_chip.options" field.

| * mtd: nand: consolidate redundant flash-based BBT flagsBrian Norris2011-09-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch works with the following three flags from two headers (nand.h and bbm.h): (1) NAND_USE_FLASH_BBT (nand.h) (2) NAND_USE_FLASH_BBT_NO_OOB (nand.h) (3) NAND_BBT_NO_OOB (bbm.h) These flags are all related and interdependent, yet they were in different headers. Flag (2) is simply the combination of (1) and (3) and can be eliminated. This patch accomplishes the following: * eliminate NAND_USE_FLASH_BBT_NO_OOB (i.e., flag (2)) * move NAND_USE_FLASH_BBT (i.e., flag (1)) to bbm.h It's important to note that because (1) and (3) are now both found in bbm.h, they should NOT be used in the "nand_chip.options" field. I removed a small section from the mtdnand DocBook because it referes to NAND_USE_FLASH_BBT in nand.h, which has been moved to bbm.h.

* ARM: orion5x: use safer FPGA ID 'default' for TS-78xxAlexander Clouter2011-03-051-5/+14
| | | | | | | | | | | | | | | | | | Originally the FPGA ID checking switch statement left disabled all the TS implemented FPGA devices if the ID was unknown to it. Michael Spang created a fix in f9b1184e that changed the default to enable the devices in the event TS silently release more revisions into the wild, this unfortunately breaks custom FPGA bitstreams. This patch amends the switch statement so that the TS devices are only enabled if on the revision number is unknown (whilst the magic matches).

* ARM: Remove dependency of plat-orion time code on mach directory includes.Lennert Buytenhek2011-03-031-0/+1
| | | | | | | | | | | This patch makes the various mach dirs that use the plat-orion time code pass in timer and bridge addresses explicitly, instead of having plat-orion get those values by including a mach dir include file -- the latter mechanism is problematic if you want to support multiple ARM platforms in the same kernel image.

* [ARM] orion5x: TS-78xx support for 'hotplug' of FPGA devicesAlexander Clouter2009-02-061-55/+196
| | | | | | | | | | | | | | | the FPGA on the TS-7800 provides access to a number of devices and so we have to be careful when reprogramming it. As we are effectively turning a bus off/on we have to inform the kernel that it should stop using anything provided by the FPGA (currently only the RTC however the NAND, LCD, etc is to come) before it's reprogrammed. Once reprogramed, we can tell the kernel to (re)enable things by checking the FPGA ID against a lookup table for what a particular FPGA bitstream can provide.

* mv643xx_eth: remove force_phy_addr fieldLennert Buytenhek2008-09-051-2/+1
| | | | | | | | | | | | | | | Currently, there are two different fields in the mv643xx_eth_platform_data struct that together describe the PHY address -- one field (phy_addr) has the address of the PHY, but if that address is zero, a second field (force_phy_addr) needs to be set to distinguish the actual address zero from a zero due to not having filled in the PHY address explicitly (which should mean 'use the default PHY address'). If we are a bit smarter about the encoding of the phy_addr field, we can avoid the need for a second field -- this patch does that. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>
