add basic support for raspberry pi2
Introduce new board symbols for embedded systems, which use
the similar board as basis. As for example raspberry pi and
raspberry pi2.
And some more updates:
Update binutils to 2.25, set gcc 4.9.2 as default.
Update glibc to 2.21, set as default.
Update gdb to 7.8.2.
Update kodi to latest release.

May 2014 01:37:54 +0200 +Subject: [PATCH] mount tmpfs-as-rootfs (initramfs) with -o + nr_blocks=0,nr_inodes=0 + +I would have preferred to write this patch to be able to pass +rootflags=nr_blocks=0,nr_inodes=0 on the kernel command line, +and then hand these rootflags over to the initramfs (tmpfs) +mount in the same way the kernel hands them over to the block +device rootfs mount. But at least the Debian/m68k initrd also +parses $rootflags from the environment and adds it to the call +to the user-space mount for the eventual root device, which +would make the kernel command line rootflags option be used in +both places (tmpfs and e.g. ext4) which is guaranteed to error +out in at least one of them. + +This change is intended to aid people in a setup where the +initrd is the final root filesystem, i.e. not mounted over. +This is especially useful in automated tests running on qemu +for boards with constrained memory (e.g. 64 MiB on sh4). + +Considering that the initramfs is normally emptied out then +overmounted, this change is probably safe for setups where +initramfs just hosts early userspace, too, since the tmpfs +backing it is not accessible any more later on, AFAICT. + +Signed-off-by: Thorsten Glaser <tg@mirbsd.org> +--- + init/do_mounts.c | 4 ++++ + 1 file changed, 4 insertions(+) + +diff --git a/init/do_mounts.c b/init/do_mounts.c +index 82f2288..55a4cfe 100644 +--- a/init/do_mounts.c ++++ b/init/do_mounts.c +@@ -594,6 +594,7 @@ out: + } + + static bool is_tmpfs;

Important events include console switches and video ++mode switches (the kernel requests background images and configuration ++parameters for the current console). The fbcondecor helper must be accessible at ++all times. If it's not, fbcondecor will be switched off automatically. ++ ++It's possible to set path to the fbcondecor helper by writing it to ++/proc/sys/kernel/fbcondecor. ++ ++***************************************************************************** ++ ++The information below is mostly technical stuff. There's probably no need to ++read it unless you plan to develop a userspace helper. ++ ++The fbcondecor protocol ++----------------------- ++ ++The fbcondecor protocol defines a communication interface between the kernel and ++the userspace fbcondecor helper. ++ ++The kernel side is responsible for: ++ ++ * rendering console text, using an image as a background (instead of a ++ standard solid color fbcon uses), ++ * accepting commands from the user via ioctls on the fbcondecor device, ++ * calling the userspace helper to set things up as soon as the fb subsystem ++ is initialized. ++ ++The userspace helper is responsible for everything else, including parsing ++configuration files, decompressing the image files whenever the kernel needs ++it, and communicating with the kernel if necessary. ++ ++The fbcondecor protocol specifies how communication is done in both ways: ++kernel->userspace and userspace->helper. ++ ++Kernel -> Userspace ++------------------- ++ ++The kernel communicates with the userspace helper by calling it and specifying ++the task to be done in a series of arguments. ++ ++The arguments follow the pattern: ++<fbcondecor protocol version> <command> <parameters> ++ ++All commands defined in fbcondecor protocol v2 have the following parameters: ++ virtual console ++ framebuffer number ++ theme ++ ++Fbcondecor protocol v1 specified an additional 'fbcondecor mode' after the ++framebuffer number. Fbcondecor protocol v1 is deprecated and should not be used. ++ ++Fbcondecor protocol v2 specifies the following commands: ++ ++getpic ++------ ++ The kernel issues this command to request image data. It's up to the ++ userspace helper to find a background image appropriate for the specified ++ theme and the current resolution. The userspace helper should respond by ++ issuing the FBIOCONDECOR_SETPIC ioctl. ++ ++init ++---- ++ The kernel issues this command after the fbcondecor device is created and ++ the fbcondecor interface is initialized. Upon receiving 'init', the userspace ++ helper should parse the kernel command line (/proc/cmdline) or otherwise ++ decide whether fbcondecor is to be activated. ++ ++ To activate fbcondecor on the first console the helper should issue the ++ FBIOCONDECOR_SETCFG, FBIOCONDECOR_SETPIC and FBIOCONDECOR_SETSTATE commands, ++ in the above-mentioned order. ++ ++ When the userspace helper is called in an early phase of the boot process ++ (right after the initialization of fbcon), no filesystems will be mounted. ++ The helper program should mount sysfs and then create the appropriate ++ framebuffer, fbcondecor and tty0 devices (if they don't already exist) to get ++ current display settings and to be able to communicate with the kernel side. ++ It should probably also mount the procfs to be able to parse the kernel ++ command line parameters. ++ ++ Note that the console sem is not held when the kernel calls fbcondecor_helper ++ with the 'init' command. The fbcondecor helper should perform all ioctls with ++ origin set to FBCON_DECOR_IO_ORIG_USER. ++ ++modechange ++---------- ++ The kernel issues this command on a mode change. The helper's response should ++ be similar to the response to the 'init' command. Note that this time the ++ console sem is held and all ioctls must be performed with origin set to ++ FBCON_DECOR_IO_ORIG_KERNEL. ++ ++ ++Userspace -> Kernel ++------------------- ++ ++Userspace programs can communicate with fbcondecor via ioctls on the ++fbcondecor device. These ioctls are to be used by both the userspace helper ++(called only by the kernel) and userspace configuration tools (run by the users). ++ ++The fbcondecor helper should set the origin field to FBCON_DECOR_IO_ORIG_KERNEL ++when doing the appropriate ioctls. All userspace configuration tools should ++use FBCON_DECOR_IO_ORIG_USER. Failure to set the appropriate value in the origin ++field when performing ioctls from the kernel helper will most likely result ++in a console deadlock. ++ ++FBCON_DECOR_IO_ORIG_KERNEL instructs fbcondecor not to try to acquire the console ++semaphore. Not surprisingly, FBCON_DECOR_IO_ORIG_USER instructs it to acquire ++the console sem. ++ ++The framebuffer console decoration provides the following ioctls (all defined in ++linux/fb.h): ++ ++FBIOCONDECOR_SETPIC ++description: loads a background picture for a virtual console ++argument: struct fbcon_decor_iowrapper*; data: struct fb_image* ++notes: ++If called for consoles other than the current foreground one, the picture data ++will be ignored. ++ ++If the current virtual console is running in a 8-bpp mode, the cmap substruct ++of fb_image has to be filled appropriately: start should be set to 16 (first ++16 colors are reserved for fbcon), len to a value <= 240 and red, green and ++blue should point to valid cmap data. The transp field is ingored. The fields ++dx, dy, bg_color, fg_color in fb_image are ignored as well. ++ ++FBIOCONDECOR_SETCFG ++description: sets the fbcondecor config for a virtual console ++argument: struct fbcon_decor_iowrapper*; data: struct vc_decor* ++notes: The structure has to be filled with valid data. ++ ++FBIOCONDECOR_GETCFG ++description: gets the fbcondecor config for a virtual console ++argument: struct fbcon_decor_iowrapper*; data: struct vc_decor* ++ ++FBIOCONDECOR_SETSTATE ++description: sets the fbcondecor state for a virtual console ++argument: struct fbcon_decor_iowrapper*; data: unsigned int* ++ values: 0 = disabled, 1 = enabled. ++ ++FBIOCONDECOR_GETSTATE ++description: gets the fbcondecor state for a virtual console ++argument: struct fbcon_decor_iowrapper*; data: unsigned int* ++ values: as in FBIOCONDECOR_SETSTATE ++ ++Info on used structures: ++ ++Definition of struct vc_decor can be found in linux/console_decor.h.
