      mailbox/omap: move the OMAP mailbox framework to drivers · c869c75c
      Suman Anna 提交于
      The mailbox hardware (in OMAP) uses a queued mailbox interrupt
      mechanism that provides a communication channel between processors
      through a set of registers and their associated interrupt signals
      by sending and receiving messages.
      
      The OMAP mailbox framework/driver code is moved to be under
      drivers/mailbox, in preparation for adapting to a common mailbox
      driver framework. This allows the build for OMAP mailbox to be
      enabled (it was disabled during the multi-platform support).
      
      As part of the migration from plat and mach code:
      - Kconfig symbols have been renamed to build OMAP1 or OMAP2+ drivers.
      - mailbox.h under plat-omap/plat/include has been split into a public
        and private header files. The public header has only the API related
        functions and types.
      - The module name mailbox.ko from plat-omap is changed to
        omap-mailbox.ko
      - The module name mailbox_mach.ko from mach-omapX is changed as
          mailbox_omap1.ko for OMAP1
          mailbox_omap2.ko for OMAP2+

      USB: OMAP: ISP1301 needs USB_PHY · c3c683ea
      Arnd Bergmann 提交于
      The Kconfig entry for USB_OMAP unconditionally selects USB_ISP1301,
      which is now only visible when USB_PHY is also enabled.
      
      This adds an appropriate dependency and enables USB_PHY in the omap1
      defconfig, avoiding these build warnings:
      
      warning: (USB_OHCI_HCD && USB_OMAP) selects ISP1301_OMAP which has unmet direct dependencies (USB_SUPPORT && USB_PHY && I2C && ARCH_OMAP_OTG)
      
      Also fix a Makefile typo while we're at it.

      ARM: OMAP1: Move dpll1 rates selection from config to runtime · 24ce2705
      Janusz Krzysztofik 提交于
      For still better multi-OMAP1 support, expand omap1_rate_table with flags
      for different SoC types and match them while selecting clock rates. The
      idea is stolen from current omap24xx clock rate selection algorithm.
      
      Since clkdev platform flag definitions are reused here, those had to be
      expanded with one extra entry for OMAP1710 subtype, as this is the only
      SoC for which we allow selection of the highest, 216 MHz rate.
      
      Once done, remove no longer needed clock rate configure time options.
      
      Tested on Amstrad Delta.

      ARM: OMAP1: Remove unsafe clock values from omap1_defconfig · b29e2354
      Janusz Krzysztofik 提交于
      DPLL1 reprogramming to a different rate is actually blocked inside
      omap1_select_table_rate(), resulting in the defalut rate of 60 MHz
      always used instead of the one selected in .config. OTOH, in
      omap1_defconfig we currently rely on Kconfig options for the supported
      MHz rates in case of boards which boot with dpll1 not set correctly by
      their boot loaders.
      
      This means that before we allow for reprogramming of dpll1 rate, we
      should remove all unsafe clock selections from omap1_defconfig,
      otherwise it will stop booting on boards with imperfect boot loaders,
      as it would always try to change to 216MHz.
      
      Keep only one safe clock rate per each supported xtal frequency, i.e.
      60MHZ dpll1 for 12MHz xtal and 182MHz dpll1 for 13MHz xtal.
      
      BTW, this change goes into the direction of removing all OMAP1 clock
      rate options, planned for next merge window.

      ARM: OMAP: Fix reprogramming of dpll1 rate · e9b7086b
      Tony Lindgren 提交于
      Commit a66cb345 (ARM: OMAP: Map SRAM
      later on with ioremap_exec()) moved the SRAM init to happen later
      to remove a dependency to early SoC detection for map_io.
      
      This broke booting on some boards not using Kconfig option for
      OMAP_CLOCKS_SET_BY_BOOTLOADER as the dpll1 reprogramming would
      cause the following error:

      kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT · 6a108a14
      David Rientjes 提交于
      The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
      is used to configure any non-standard kernel with a much larger scope than
      only small devices.
      
      This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
      references to the option throughout the kernel.  A new CONFIG_EMBEDDED
      option is added that automatically selects CONFIG_EXPERT when enabled and
      can be used in the future to isolate options that should only be
      considered for embedded systems (RISC architectures, SLOB, etc).
      
      Calling the option "EXPERT" more accurately represents its intention: only
      expert users who understand the impact of the configuration changes they
      are making should enable it.

      Then change few things manually, like use Nokia 770 CONFIG_CMDLINE
