arc: get rid of running_on_hw

2016-04-11T17:20:30+00:00

ISS is obsolete now and nSIM is used for simulation instead.
In its turn nSIM properly handles baud-rate settings so get rid
of now useless check.

dm: serial: Remove duplicated carriage return character

2016-03-14T21:34:50+00:00

As the handling for carriage return and line feed is done in the common
DM driver serial-uclass.c, such handling in some serial DM drivers is
duplicated and need to be removed.

dm: Use dev_get_addr() where possible

2015-08-31T13:57:26+00:00

This is a convenient way for a driver to get the hardware address of a
device, when regmap or syscon are not being used. Change existing callers
to use it as an example to others.

Now when all infrastructure in ARC is ready for it let's switch ARC UART
to driver model.

serial/serial_arc: set registers address during compilation

2015-04-03T06:47:49+00:00

Being global variable with 0 value it falls into .bss area which we may
only use after relocation to RAM. And right afetr relocation we zero
.bss - effectively cleaing register address set for early console.

Now with pre-set value "regs" variable is no longer in .bss and this way
safely survives relocation.

serial: arc: Convert to use default_serial_puts

2014-02-21T14:50:12+00:00

Use default_serial_puts() instead of duplicating the implementation.

serial/serial_arc: switch from {read|write}l to {read|write}b accessors

2014-02-21T12:54:05+00:00

This is required for proper functionality on big-endian targets.
Memory-mapped registres of ARC UART are not 32-bit words but 8-bit bytes
so on little-endian target either acessor (_l or _b) works fine.
On big-endian only _b accessors works as expected.
