      [MTD] Fixes of performance and stability issues in CFI driver. · 46a1652c
      由 Alexey Korolev 提交于 
      Fix of performance and stability issues on Intel NOR chips. It fixes:

1. Very low write performance on Sibley (perf tests demonstrated write
   performance less than 100Kb/sec when it should be over 400Kb/sec).

2. Low erase performance. (perf tests on Sibleuy demonstrated erase
   performance 246Kb/sec when it should be over 300Kb/sec).

3. Error on JFFS2 tests with CPU loading application when MTD returns
   "block erase error: (status timeout)" To fix the issue it does the
   following:
     1. Removes the timeout tuning from inval_cache_and_wait_for_operation.
     2. Waiting conditions in inval_cache_and_wait_for_operation now is
         based on timer resolution
        If timeout is lower than timer resolution then we do in cycle
	  "Checking the status"
	  udelay(1);
	  cond_resched();
        If timeout is greater than timer resolution (probably erase
        operation) We do the following
	  sleep for half of operation timeout and do in cycle the following
	    "Checking the status"
	    sleep for timer resolution

      block2mtd.c: Make kernel boot command line arguments work (try 4) · c4e7fb31
      由 Ville Herva 提交于 
      Trying to pass kernel command line arguments to block2mtd at boot-time does
not work currently. block2mtd_setup() is called so early that kmalloc()
fails nevermind being able to do open_bdev_excl() (which requires rootfs to
be mounted. This patch only saves the option string at the early boot stage,
and parses them later when block2mtd_init() is called. If open_bdev_excl()
fails, open_by_devnum(name_to_dev_t()) is tried instead, which makes it
possible to initialize the driver before rootfs has been mounted. Also gets
rid of the superfluous parse_name() that only checks if name is longer than
80 chars and copies it to a string that is not kfreed.

With this patch, I can boot statically compiled block2mtd, and mount jffs2
as rootfs (without modules or initrd), with lilo config like this:

   root=/dev/mtdblock0
   append="rootfstype=jffs2 block2mtd.block2mtd=/dev/hdc2,65536"

(Note that rootfstype=jffs2 is required, since the kernel only tries
filesystems without "nodev" attribute by default, and jffs is "nodev").

Compared to first version of this patch, this one does not copy the
parameters to the global buffer if init has already been called, and the
global array is marked as __initdata.

Compared to the second version of this patch, module build is fixed.

Compared to the third version of this patch, statically compiled block2mtd
driver with no boot-time parameter no longer gives spurious error 'cannot
open device ""'

      remove #error on !PCI from pmc551.c · 9d05cd51
      由 Rolf Eike Beer 提交于 
      PMC551 depends on PCI in Kconfig so there is no need to #error in code if PCI
is not set.
