This is a backport of the patches accepted to the Linux mainline related to mvebu SoC (Armada XP and Armada 370) between Linux v3.10, and Linux v3.11. This work mainly covers: * Enabling USB storage, and PCI to mvebu_defconfig. * Add support for NOR flash. * Some PCI device tree related updates, and bus parsing. * Adding Armada XP & 370 PCI driver, and update some clock gating specifics. * Introduce Marvell EBU Device Bus driver. * Enaling USB in the armada*.dts. * Enabling, and updating the mvebu-mbus. * Some SATA and Ethernet related fixes.

Subject: [PATCH 026/203] arm: mvebu: move cache and mvebu-mbus initialization
|
|
later
|
|
|
|
Current, the L2 cache and the mvebu-mbus drivers are initialized at
|
|
->init_early() time. However, at ->init_early() time, ioremap() only
|
|
works if a static I/O mapping has already been put in place. If it's
|
|
not the case, it tries to do a memory allocation with kmalloc() which
|
|
is not possible so early at this stage of the initialization.
|
|
|
|
Since we want to get rid of the static I/O mapping, we cannot
|
|
initialize the L2 cache driver and the mvebu-mbus driver so early. So,
|
|
we move their initialization to the ->init_time() level, which is
|
|
slightly later (so ioremap() works properly), but sufficiently early
|
|
to be before the call of the ->smp_prepare_cpus() hook, which creates
|
|
an address decoding window for the BootROM, which requires the
|
|
mvebu-mbus driver to be properly initialized.
