Revert "serial: ns16550: Add RX interrupt buffer support"

This reverts commit 6822cf3ec7c8768b8727573b8f4b2cb3d870b881.

As Bin Meng has tested and pointed out, we don't need the RX interrupt
for the RX buffer support at all. Just reading all available characters
into a buffer is sufficient to solve the problem with the dropped
characters upon long lines pasted into the U-Boot prompt. Since this
RX buffer support can be implemented in a generic way, without any
device specifica (e.g. for the ns16550), I'll post a new patch with
a new serial RX buffer support for DM, which all DM based serial
drivers can use.

x86: fsp: Configure SPI opcode registers before SPI is locked down

Some Intel FSP (like Braswell) does SPI lock-down during the call
to fsp_notify(INIT_PHASE_BOOT). But before SPI lock-down is done,
it's bootloader's responsibility to configure the SPI controller's
opcode registers properly otherwise SPI controller driver doesn't
know how to communicate with the SPI flash device.

This introduces a Kconfig option CONFIG_FSP_LOCKDOWN_SPI for such
FSPs. When it is on, U-Boot will configure the SPI opcode registers
before the lock-down.

x86: ich-spi: Don't read cached lock status

At present the ICH SPI controller driver reads the controller lock
status from its register in the probe routine and saves the lock
status to a member of priv. Later the driver uses the cached status
from priv to judge whether the controller setting is locked and do
different setup.

But such logic is only valid when there is only the SPI controller
driver that touches the SPI hardware. In fact the lock status change
can be trigged outside the driver, eg: during the fsp_notify() call
when Intel FSP is used.

This changes the driver to read the lock status every time when an
SPI transfer is initiated instead of reading the cached one.

7 years agohash: Compile only hardware or software versions of SHA algorithms
Tom Rini [Mon, 14 Aug 2017 20:38:07 +0000 (16:38 -0400)]
hash: Compile only hardware or software versions of SHA algorithms

Commit 089df18bfe9d ("lib: move hash CONFIG options to Kconfig") moved
CONFIG_SHA1, CONFIG_SHA256, CONFIG_SHA_HW_ACCEL, and
CONFIG_SHA_PROG_HW_ACCEL config options to Kconfig. So in the case of
SPL, CONFIG_SPL_HASH_SUPPORT enables CONFIG_SHA1 and CONFIG_SHA256 which
enables SHA SW library by default.  But in the case of platforms with
SHA HW library support, SHA SW library becomes redundant and increases
size of SPL by approx 18K.  Rework the code so that we have named
members and only have either software or hardware versions of the
algorithm, depending on the relevant config options.  Update the comment
around hash_algo to reflect this as well.

7 years agoMakefile: honor PYTHON configuration properly
Clément Bœsch [Mon, 14 Aug 2017 06:59:11 +0000 (08:59 +0200)]
Makefile: honor PYTHON configuration properly

On some systems `python` is `python3` (for instance, Archlinux). The
`PYTHON` variable can be used to point to `python2` to have a successful
build.

The use of `PYTHON` is currently limited in the Makefile and needs to be
extended in other places:

First, pylibfdt is required to be a Python 2 binding (binman imports
pylibfdt and is only compatible Python 2), so its setup.py needs to be
called accordingly. An alternative would be to change the libfdt
setup.py shebang to python2, but the binding is actually portable. Also,
it would break on system where there is no such thing as `python2`.

Secondly, the libfdt import checks need to be done against Python 2 as
well since the Python 2 compiled modules (in this case _libdft.so) can
not be imported from Python 3.

Note on the libfdt imports: "@if ! PYTHONPATH=tools $(PYTHON) -c 'import
libfdt'; then..." is probably simpler than the currently sub-optimal
pipe.

dm: blk: Add a generic function for block device commands

Most block devices provide a command (e.g. 'sata', 'scsi', 'ide') and
these commands generally do the same thing. This makes it harder to
maintain this code and keep it consistent.

We now have a block device interface which is either implemented by driver
model (when CONFIG_BLK is enabled) or with a legacy interface. Therefore
it is possible to handle most of what these commands do with generic code.

Add a new generic function to process block-device commands using the
interface type and the current device number for that type.
