common: console: Fix duplicated CONFIG in silent env callback

2017-08-28T11:19:12+00:00

The silent environment callback function does not update the silent
flag during silent env set or unset. That is because of duplicated
CONFIG keyword at preprocessor condition in silent environment
callback function and cause silent env callback unable to work.

This patch is to remove the duplicated CONFIG keywork in silent
environment callback function.

env: Rename getenv/_f() to env_get()

2017-08-16T12:30:24+00:00

We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.

Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.

dm: console: Check for serial devices properly

2017-07-31T16:21:40+00:00

With driver model the serial device is often not called "serial". Mark
driver-model stdio devices so that they can be detected and we can look up
the uclass. This is a more reliable way of finding out whether the console
is connected to a serial device or not.

console: Unify the check for a serial console

2017-07-31T16:21:40+00:00

Put the check for whether a console is a serial device in a function so
that we can share the code in the two places that use it.

console: simplify puts()

2017-07-28T18:02:47+00:00

Current puts() and putc() have similar #ifdef / if() conditionals.
Make puts() iterate over putc() to avoid code duplication.

sandbox: Drop special case console code for sandbox

2017-07-11T16:08:20+00:00

At present sandbox has a special case where it directly calls os_putc()
when it does not have a console yet.

Now that we have the pre-console buffer enabled we can drop this. Any
early characters will be buffered and output later.

console: Use map_sysmem() for the pre-relocation console

2017-07-11T16:08:19+00:00

At present this feature casts the address to a pointer. Use the
map_sysmem() function so that it will work correctly on sandbox.

Allow displaying the U-Boot banner on a video display

2017-07-11T16:08:19+00:00

At present the U-Boot banner is only displayed on the serial console. If
this is not visible to the user, the banner does not show. Some devices
have a video display which can usefully display this information.

Add a banner which is printed after relocation only on non-serial devices
if CONFIG_DISPLAY_BOARDINFO_LATE is defined.

console: Don't enable CONFIG-CONSOLE_MUX, etc. in SPL

2017-02-06T03:38:46+00:00

CONFIG_CONSOLE_MUX and CONFIG_SYS_CONSOLE_IS_IN_ENV are not applicable
for SPL. Update the console code to use CONFIG_IS_ENABLED(), so that these
options will be inactive in SPL.
