Ramakrishna Pallala 2b5b7da9f3 subsys: disk: Add support for multiple disk interfaces
Add support for enabling multiple disk interfaces (Flash, RAM)
simultaneously in Zephyr by introducing a simple disk interface
framework where we can register multiple disks which would
interface with different storage devices. This would enable us
to have multiple instances of FATFS in Zephyr.

Add support for mass storage drive disk name which will be
used as an argument when calling the disk interface API's.

Enable multiple volumes support configuration in
ELM FAT library.

Michael Hope cff16051bb disk: delete the GET_DISK_SIZE IOCTL.
The argument is a u32_t which limits the maximum disk size to 4 GiB.
Rather than fix this, delete the ioctl and switch the only use to
GET_SECTOR_COUNT instead.

Kumar Gala 6da829690f subsys: convert to using newly introduced integer sized types
Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types.

Kumar Gala 789081673f Introduce new sized integer typedefs
This is a start to move away from the C99 {u}int{8,16,32,64}_t types to
Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t.  This allows Zephyr
to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.

We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.

We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.

David B. Kinder ac74d8b652 license: Replace Apache boilerplate with SPDX tag
Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.

Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.

Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file.  Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Jithu Joseph 89f4bf7c7e subsys: disk: Refactor disk_access stuff into a directory
Disk IO functions are used by both FS and USB Mass Storage.
This patch refactors those from FS directory to a separate one.
In addition existing, config options were modified to make
stuff meaningful.
