[Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>]

Hi all,
these are the remaining unapplied patches of the ARM HDLCD patch series.


Changes in v7:
- rebased on b61ed421d2c85b5b106c63f2c14f8aa162b282f0;
- turn more printk and panic into early_printk and early_panic.

Changes in v6:
- rebased on 77d3a1db3196b1b5864469f8d3f41d496800c795;
- remove useless initializations to NULL in lfb_init;
- more compact checks in lfb_init.


Changes in v5:
- move the barriers outside the loop in flush_xen_data_tlb_range_va;
- move out of "introduce early_ioremap" any changes related to
flush_xen_data_tlb_range_va and PAGE masks;
- remove lfb_alloc and the now unused __initdata variables;
- fix indentation and long lines;
- reword commit message of "move setup_mm right after setup_pagetables";
- turn printk in setup_mm into an early_printk in setup_mm;
- actually include the Makefile for xen/arch/arm/platforms.


Changes in v4:
- rename flush_xen_data_tlb_range to flush_xen_data_tlb_range_va;
- replace all the calls to flush_xen_data_tlb_va, with calls to
flush_xen_data_tlb_range_va;
- flush the entire 2MB mapping at BOOT_MISC_VIRT_START rather than just
the first 4k;
- remove flush_xen_data_tlb_va;
- fix indentation;
- rename EARLY_VMAP_START/END to EARLY_VMAP_VIRT_START/END;
- mark early_ioremap as __init;
- reduce the amount of casts in early_ioremap;
- squash the vesa.c changes into this patch;
- rename fb* to lfb*;
- pass a pointer to fb_init;
- use %u for screen dimensions;
- specify loglevel in printk;
- call fb_free on error in fb_alloc;
- no __init on declarations;
- do not break messages to fit 80 columns;
- remove "preserve DTB mappings";
- introduce a new "move setup_mm right after setup_pagetables" patch;
- stop iterating over the DT nodes in device_tree_for_each_node if
func returns a value != 0;
- return 1 from _find_compatible_node when a node is found;
- move the wait loop and the syscfg cfgctrl write into a separate
function;
- fix comments;
- define all registers in write;
- move platform_vexpress.c to platforms/vexpress.c;
- move platform_vexpress.h to arm-arm/platforms/vexpress.h;
- use a lookup table to set the color masks;
- fix indentation;
- make sure mode_string is not NULL and is not bigger than 16 chars
before continuing;
- introduce 2 separate error messages for !hdlcd_start and
!framebuffer_start at the beginning of video_init;
- mark get_color_masks and set_pixclock as __init;
- check that we are running on a vexpress machine before calling
vexpress_syscfg.


Changes in v3:
- rename fb_cr to fb_carriage_return.


Changes in v2:
- rebase on latest xen-unstable;
- add support for multiple resolutions;
- add support to dynamically change the OSC5 motherboard timer;
- add the patch "preserve DTB mappings".
