mmc: dw_mmc: Add support for 64-bit IDMAC
Some DW MMC blocks (e.g. those on modern Exynos chips) support 64-bit
DMA addressing mode. 64-bit DW MMC variants differ from their 32-bit
counterparts:
- the register layout is a bit different (because there are additional
IDMAC registers present for storing upper part of 64-bit addresses)
- DMA descriptor structure is bigger and different from 32-bit one
Introduce all necessary changes to enable support for 64-bit DMA capable
DW MMC blocks. Next changes were made:
1. Check which DMA address mode is supported in current IP-core
version. HCON register (bit 27) indicates whether it's 32-bit or
64-bit addressing. Add boolean .dma_64bit_address field to struct
dwmci_host and store the result there. dwmci_init_dma() function is
introduced for doing so, which is called on driver's init.
2. Add 64-bit DMA descriptor (struct dwmci_idmac64) and use it in
dwmci_prepare_desc() in case if .dma_64bit_address field is true.
A new dwmci_set_idma_desc64() function was added for populating that
descriptor.
3. Add registers for 64-bit DMA capable blocks. To make the access to
IDMAC registers universal between 32-bit / 64-bit cases, a new
struct dwmci_idmac_regs (and corresponding host->regs field) was
introduced, which abstracts the hardware by being set to
appropriate offset constants on init. All direct calls to IDMAC
registers were correspondingly replaced by accessing host->regs.
4. Allocate and use 64-bit DMA descriptors buffer in case when IDMAC
is 64-bit capable. Extract all the code (except for the IDMAC
descriptors buffer allocation) from dwmci_send_cmd() to
dwmci_send_cmd_common(), so that it's possible to keep IDMAC
buffer (either 32-bit or 64-bit) on stack during send_cmd routine.
The insights for this implementation were taken from Linux kernel DW MMC
driver.

When mounting ubifs e.g. through command 'ubifsmount' one global static
superblock 'ubifs_sb' is used _and_ the requested volume is opened (like
in Linux). The pointer returned by 'ubifs_open_volume()' is stored in
that superblock struct and freed later on cmd 'ubifsumount' or another
call to 'ubifsmount' with a different volume, through ubifs_umount() and
ubi_close_volume().
In ubifs_ls(), ubifs_exists(), ubifs_size(), and ubifs_read() the volume
was opened again, which is technically no problem with regard to
refcounting, but here the still valid pointer in sb was overwritten,
leading to a memory leak. Even worse, when using one of those
functions and calling ubifsumount later, ubi_close_volume() was called
again but now on an already freed pointer, leading to a double free.
This actually crashed with different invalid memory accesses on a board
using the old distro boot and a rather long script handling RAUC
updates.
Example:
> ubi part UBI
> ubifsmount ubi0:boot
> test -e ubi ubi0:boot /boot.scr.uimg
> ubifsumount
The ubifs specific commands 'ubifsls' and 'ubifsload' check for a
mounted volume by themselves, for the generic fs variants 'ls', 'load',
(and 'size', and 'test -e') this is covered by special ubifs handling in
fs_set_blk_dev() and deeper down blk_get_device_part_str() then. So for
ubifs_ls(), ubifs_exists(), ubifs_size(), and ubifs_read() we can be
sure the volume is opened and the necessary struct pointer in sb is
valid, so it is not needed to open volume again.
