Introduce some macros and helpers to avoid magic numbers and
rename macros/functions for clarification.
- We see '| 2' in several places. This means Data Cycle in MAP11 mode.
The Denali User's Guide says bit[1:0] of MAP11 is like follows:
b'00 = Command Cycle
b'01 = Address Cycle
b'10 = Data Cycle
So, this commit added DENALI_MAP11_{CMD,ADDR,DATA} macros.
- We see 'denali->flash_mem + 0x10' in several places, but 0x10 is a
magic number. Actually, this accesses the data port of the Host
Data/Command Interface. So, this commit added DENALI_HOST_DATA.
On the other hand, 'denali->flash_mem' gets access to the address
port, so DENALI_HOST_ADDR was also added.
- We see 'index_addr(denali, cmd, 0x1)' in denali_erase(), but 0x1
is a magic number. 0x1 means the erase operation. Replace 0x1
with DENALI_ERASE.
- Rename index_addr() to denali_host_write() for clarification
- Denali User's Guide says MAP{00,01,10,11} for access mode. Match
the macros with terminology in the IP document.
- Rename struct members as follows:
flash_bank -> active_bank (currently selected bank)
flash_reg -> reg (base address of registers)
flash_mem -> host (base address of host interface)
devnum -> devs_per_cs (devices connected in parallel)
bbtskipbytes -> oob_skip_bytes (number of bytes to skip in OOB)

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
