With recent changes, barebox can handle partitions bigger than 4G.
Remove the todo.

The 16-bit port has experienced bitrot and failed to compile with more
recent linkers for at least a year. Fixing the linker error is insufficient
to restore a barebox that can boot to shell. This continued breakage likely
means that there are no users interested in updating. As new x86 projects
should be using MACH_EFI_GENERIC anyway, retire support for 16-bit legacy
boot (MACH_X86_GENERIC).

-x86
-===
-
-.. note::
-   This is about legacy x86 PC boot, which is not as well supported as booting
-   under UEFI. Refer to :doc:`boards/efi.rst` for documentation on the barebox
-   EFI support.
-
-Features
---------
-
-barebox can act as a bootloader for PC based systems. In this case a special
-binary layout will be created to be able to store it on some media the PC
-BIOS can boot from. It can boot Linux kernels stored also on the same boot
-media and be configured at runtime, with the possibility to store the changed
-configuration on the boot media.
-
-Restrictions
-------------
-
-Due to some BIOS and barebox restrictions the boot media must be
-prepared in some special way:
-
-  * barebox must be stored in the MBR (Master Boot Record) of the boot
-    media. Currently its not possible to store and boot it in one of
-    the partition sectors to use it as a second stage loader). This is
-    no eternal restriction. It only needs further effort to add this
-    feature.
-  * barebox currently cannot run a chained boot loader. Also, this is
-    no external restriction, only further effort needed.
-  * barebox comes with limited filesystem support. There is currently
-    no support for the most common and popular filesystems used in the
-    \*NIX world. This restricts locations where to store a kernel and
-    other runtime information
-  * barebox must be stored to the first n sectors of the boot media.
-    To ensure this does not collide with partitions on the boot media,
-    the first partition must start at a sector behind the ones barebox
-    occupies.
-  * barebox handles its runtime configuration in a special way: It
-    stores it in a binary way into some reserved sectors ("persistant
-    storage").
-
-Boot Preparations
------------------
-
-To store the barebox image to a boot media, it comes with the tool
-setupmbr in the directory  scripts/setupmbr/ . To be able to use it on
-the boot media of your choice, some preparations are required.
-
-Keep Sectors free
------------------
-
-Build the barebox image and check its size. At least this amount of
-sectors must be kept free after the MBR prior the first partition. Do this
-simple calulation:
-
-.. code-block:: none
-
-  sectors = (size of barebox image + 511) / 512
-
-To be able to store the runtime configuration, further free sectors are
-required. Its up to you and your requirements, how large this persistant
-storage must be. If you need 16 kiB for this purpose, you need to keep
-additional 32 sectors free.
-
-For this example we are reserving 300 sectors for the barebox image and
-additionaly 32 sectors for the persistant storage. So, the first partition on
-the boot media must start at sector 333 or later.
-
-Run the  fdisk tool to setup such a partition table:
-
-.. code-block:: none
-
-  [jb@host]~> fdisk /dev/sda
-  Command (m for help): p
-  
-  Disk /dev/sda: 20.7 MB, 212680704 bytes
-  16 heads, 63 sectors/track, 406 cylinders
-  Units = cylinders of 1008 * 512 = 516096 bytes
-  
-  Device Boot      Start         End      Blocks   Id  System
-
-Change the used units to  sectors for easier handling.
-
-.. code-block:: none
-
-  Command (m for help): u
-  Changing display/entry units to sectors
-  
-  Command (m for help): p
-
-  Disk /dev/sda: 20.7 MB, 212680704 bytes
-  16 heads, 63 sectors/track, 406 cylinders, total 409248 sectors
-  Units = sectors of 1 * 512 = 512 bytes
-  
-  Device Boot      Start         End      Blocks   Id  System
-
-Now its possible to create the first partition with the required offset:
-
-.. code-block:: none
-
-  Command (m for help): n
-  Command action
-     e   extended
-     p   primary partition (1-4)
-  p
-  Partition number (1-4): 1
-  First sector (63-409247, default 63): 333
-  Last sector or +size or +sizeM or +sizeK (333-409247, default 409247): +18M
-  Command (m for help): p
-  
-  Disk /dev/sda: 20.7 MB, 212680704 bytes
-  16 heads, 63 sectors/track, 406 cylinders, total 409248 sectors
-  Units = sectors of 1 * 512 = 512 bytes
-  
-          Device Boot      Start         End      Blocks   Id  System
-  /dev/sda                   333       35489       17578+  83  Linux
-
-That's all. Do whatever is required now with the new partition (formatting
-and populating the root filesystem for example) to make it useful.
-
-In the next step, barebox gets installed to this boot media::
-
-  [jb@host]~> scripts/setupmbr/setupmbr -s 32 -m ./barebox -d /dev/sda
-
-This command writes the barebox image file './barebox' onto the device
- /dev/sda.
-
-The  -s option will keep the persistant storage sectors free and untouched
-and set flags in the MBR to forward its existance, size and location to
-barebox at runtime.  setupmbr also does not change the partition table.
-
-The barebox image gets stored on the boot media like this::
-
-  sector 0   1             33                              333
-         |---|-------------|--------------- ~~~ ------------|--------------
-        MBR    persistant              barebox                 first
-                storage               main image              partition
-
-If the  -s option is omitted, the "persistant storage" part simply does
-not exist:
-
-.. code-block:: none
-
-  sector 0   1                              333
-         |---|--------------- ~~~ ------------|--------------
-        MBR               barebox                 first
-                         main image              partition
-
-**NOTE:** the ``setupmbr`` tool is also working on real image file than on device
-nodes only. So, there is no restriction what kind of file will be
-modified.

-/**
- * @file
- * @brief Media communication layer through the standard 16 bit PC-BIOS
- *
- * This communication driver does all accesses to the boot medium via 16 bit
- * real mode calls into the standard BIOS. Due to this method, its possible
- * to use all the medias to boot from that are supported by the BIOS. This
- * also includes emulated only medias.
- *
- * To be able to call the real mode BIOS, this driver must switch back to
- * real mode for each access. This will slow down the access a little bit, but
- * we are a boot loader here, not an operating system...
- *
- * Note: We need scratch memory for the BIOS communication, because the BIOS
- * can only handle memory below 0xA0000. So we must copy all data between
- * the flat mode buffers and realmode buffers.
- *
- * Note: This driver makes no sense on other architectures than x86.
- *
- * Note: This driver does only support LBA addressing. Currently no CHS!
