10 years agoARM: cache: Move the cp15 CR register read before flushing the cache.
SRICHARAN R [Wed, 16 May 2012 23:52:54 +0000 (23:52 +0000)]
ARM: cache: Move the cp15 CR register read before flushing the cache.

The following is the cleanup sequence in arch/arm/cpu/armv7/cpu.c

int cleanup_before_linux(void)
{
 ...
 ...
 dcache_disable();
 v7_outer_cache_disable();
 invalidate_dcache_all();
}

 1) invalidate_dcache_all call expects that all the caches has been
 flushed, invalidated and there are no dirty entries prior to its
 execution.  In the above sequence dcache_disable() flushes, invalidates
 the caches and turns off the  mmu. But after it cleanups the cache
 and before the mmu is disabled  there is a cp_delay() function which
 has STR instruction. On certain cores like the cortex-a15, cache hit
 and a write can happen to a cache line even when the dcache is
 disabled. So the above mentioned STR instruction creates a dirty entry
 after cleaning. The mmu gets disabled after this.

 2) invalidate_dcache_all invalidates the cache lines. Again on
 cores like cortex-a15, invalidate instruction flushes the dirty
 line as well. So some times the dirty line from sequence 1
 can corrupt the memory resulting in a crash.

 Fixing this by moving the get_cr() and cp_delay() calls before
 cleaning up the cache, thus avoiding the dirty entry.

net: Multiple updates/enhancements to designware.c

This patch adds the following changes to designware ethernet driver
found on the ST SPEAr SoC:

- Don't init MAC & PHY upon startup. This causes a delay, waiting for
  the auto negotiation to complete. And we don't want this delay to
  always happen. Especially not on platforms where ethernet is not
  used at all (e.g. booting via flash).
  Instead postpone the MAC / PHY configuration to the stage, where
  ethernet is first used.
- Add possibility for board specific PHY init code. This is needed
  for example on the X600 board, where the Vitesse PHY needs to be
  configured for GMII mode.
  This board specific PHY init is done via the function
  designware_board_phy_init(). And this driver now adds a weak default
  which can be overridden by board code.
- Use common functions miiphy_speed() & miiphy_duplex() to read
  link status from PHY.
- Print status and progress of auto negotiation.
- Print link status (speed, dupex) upon first usage.

board_init, which should be early enough in the boot sequence. The only
calls that could not be moved is the one for the SOFT (bitbang) I2C, and

Description: The refresh rate is programmed in the EMIF_SDRAM_REF_CTRL[15:0]
REG_REFRESH_RATE parameter taking into account frequency of the device.
When a warm reset is applied on the system, the OMAP processor restarts
with another OPP and so frequency is not the same. Due to this frequency
change, the refresh rate will be too low and could result in an unexpected
behavior on the memory side.

Workaround:
The workaround is to force self-refresh when coming back from the warm reset
with the following sequence:
• Set EMIF_PWR_MGMT_CTRL[10:8] REG_LP_MODE to 0x2
• Set EMIF_PWR_MGMT_CTRL[7:4] REG_SR_TIM to 0x0
• Do a dummy read (loads automatically new value of sr_tim)
This will reduce the risk of memory content corruption, but memory content
can't be guaranteed after a warm reset.

arm/km: use spi claim bus to switch between SPI and NAND

We overwrite these weak functions from the kirkwood spi code to
use our own method to be able to switch between the SPI NOR and
the NAND flash. This is needed e.g. to update the u-boot. The former
command do_spi_toggle can therefore be removed. And the usage of
this command is removed from the u-boot update command in the
u-boot environment.

10 years agoARM: don't probe PHY address for LaCie boards

ARM: don't probe PHY address for LaCie boards

The command miiphy_read(name, 0xEE, 0xEE, (u16 *) &devadr) always
returns 8 for the PHY address. It is the reset value for the PHY
Address Register. Obviously, this default value could be incorrect.
Moreover, as the PHY address is well known, there is no need to
auto-detect it.

Now, the PHY address must given as a parameter to the PHY initialization
function. Additionally this patch also fixes some aesthetic issues.
