Revert "sandbox: Drop special case console code for sandbox"

2017-12-07T20:17:00+00:00

While sandbox works OK without the special-case code, it does result in
console output being stored in the pre-console buffer while sandbox starts
up. If there is a crash or a problem then there is no indication of what
is going on.

For ease of debugging it seems better to revert this change also.

This reverts commit d8c6fb8cedbc35eee27730a7fa544e499b3c81cc.

Revert "console: simplify puts()"

2017-11-12T21:18:16+00:00

This reverts commit c61d0009feb966e0e93254a8c435a1889085e6b8.

A tbs2910 board user reported a very slow console frambuffer as
regression in current u-boot. I could bisect this down to the
above mentioned commit.

This revert brings back the fast framebuffer console (one
cache flush per string in puts(), not after each char).

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.
