  • If running in the Normal World on a TrustZone-enabled SoC, Linux
    does not have complete control over the L2 cache controller
    configuration. The kernel cannot work reliably on such platforms
    without the l2x0 cache support code built in.

    This patch unconditionally enables l2x0 support for the OMAP4 SoCs.

    Thanks to Rob Herring for this suggestion. [1]

  • Making SMP depend on (huge list of MACH_ and ARCH_ configs) is
    bothersome to maintain and likely to lead to merge conflicts.

    This patch moves the knowledge of which platforms are SMP-capable

  • Making CACHE_L2X0 depend on (huge list of MACH_ and ARCH_ configs)
    is bothersome to maintain and likely to lead to merge conflicts.

    This patch moves the knowledge of which platforms have a L2x0 or
    PL310 cache controller to the individual machines. To enable this,
    a new MIGHT_HAVE_CACHE_L2X0 config option is introduced to allow
    machines to indicate that they may have such a cache controller
    independently of each other.

    Boards/SoCs which cannot reliably operate without the L2 cache
    controller support will need to select CACHE_L2X0 directly from
    their own Kconfigs instead. This applies to some TrustZone-enabled
    boards where Linux runs in the Normal World, for example.

  • sched_clock() is yet another blocker on the road to the single
    image. This patch implements an idea by Russell King:

    http://www.spinics.net/lists/linux-omap/msg49561.html

    Instead of asking the platform to implement both sched_clock()
    itself and the rollover callback, simply register a read()
    function, and let the ARM code care about sched_clock() itself,
    the conversion to ns and the rollover. sched_clock() uses
    this read() function as an indirection to the platform code.
    If the platform doesn't provide a read(), the code falls back
    to the jiffy counter (just like the default sched_clock).

    This allow some simplifications and possibly some footprint gain
    when multiple platforms are compiled in. Among the drawbacks,
    the removal of the *_fixed_sched_clock optimization which could
    negatively impact some platforms (sa1100, tegra, versatile
    and omap).

    Tested on 11MPCore, OMAP4 and Tegra.

  • Local timer clock is sourced from the CPU clock and hence changes
    along with CPU clock. These per CPU local timers are used as
    clock-events, so they need to be reconfigured on CPU frequency
    change as part of CPUfreq governor.

    Newly introduced clockevents_reconfigure() needs to know the
    twd clock-rate. Provide a clock-node to make clk_get_rate() work
    for TWD.

    Note: For such module, the state is managed automatically by HW according
    to clock domain transition. It is then not possible to wait for idle even
    later in the _idle function since the status will change at clock domain
    boundary.

    _wait_target_disable() into _disable_module(), removing duplicate code]

  • AM3517/3505 chips don't have voltage controller and voltage processor
    IP blocks. Trying to use OMAP34xx/36xx voltage domain data on these
    chips causes a crash during boot:

    omap_vc_init_channel: PMIC info requried to configure vc forvdd_core not populated.Hence cannot initialize vc
    Unable to handle kernel NULL pointer dereference at virtual address 00000025
    pgd = c0004000
    [00000025] *pgd=00000000
    Internal error: Oops: 5 [#1] SMP
    Modules linked in:
    CPU: 0 Tainted: G W (3.2.0-rc5-00006-g402ecf4 #304)
    PC is at omap_vp_init+0x5c/0x14c
    LR is at omap_vp_init+0x54/0x14c

    Fix this by using very minimal voltage domain definitions for AM3517/3505.
