* removes the burden of remembering written values as needed. The
* extra work of storing the value doesn't count, since a delay is
* needed after a SCC access anyway. Additionally, _SCCwrite() manages
* writes to WR0 and WR8 differently, because these can be accessed
* directly with less overhead. Another special case are WR7 and WR7'.
* _SCCwrite automatically checks what of this registers is selected
* and changes b0 of WR15 if needed.
*
* _SCCread() for standard read registers is straightforward, except
* for RR2 (split into two "virtual" registers: one for the value
* written to WR2 (from the shadow) and one for the vector including
* status from RR2, Ch. B) and RR3. The latter must be read from
* Channel A, because it reads as all zeros on Ch. B. RR0 and RR8 can
* be accessed directly as before.
*
* The two inline function contain complicated switch statements. But
* I rely on regno and final_delay being constants, so gcc can reduce
* the whole stuff to just some assembler statements.
*
* _SCCwrite and _SCCread aren't intended to be used directly under
* normal circumstances. The macros SCCread[_ND] and SCCwrite[_ND] are
* for that purpose. They assume that a local variable 'port' is
* declared and pointing to the port's scc_struct entry. The
* variants with "_NB" appended should be used if no other SCC
* accesses follow immediately (within 0.5 usecs). They just skip the
* final delay nops.
*
* Please note that accesses to SCC registers should only take place
* when interrupts are turned off (at least if SCC interrupts are
* enabled). Otherwise, an interrupt could interfere with the
* two-stage accessing process.

This module adds support for embedded wireless adapters based on
Broadcom IEEE802.11n FullMAC chipsets. This driver uses the kernel's
wireless extensions subsystem. If you choose to build a module,
it'll be called brcmfmac.ko.

Description:
This routine takes the input number N and its q format qN and compute
the log10(N). This routine first normalizes the input no N. Then N is in mag*(2^x) format.
mag is any number in the range 2^30-(2^31 - 1). Then log2(mag * 2^x) = log2(mag) + x is computed.
From that log10(mag * 2^x) = log2(mag * 2^x) * log10(2) is computed.
This routine looks the log2 value in the table considering LOG2_LOG_TABLE_SIZE+1 MSBs.
As the MSB is always 1, only next LOG2_OF_LOG_TABLE_SIZE MSBs are used for table lookup.
Next 16 MSBs are used for interpolation.
Inputs:
N - number to which log10 has to be found.
qN - q format of N
log10N - address where log10(N) will be written.
qLog10N - address where log10N qformat will be written.
Note/Problem:
For accurate results input should be in normalized or near normalized form.
