Veerabhadrarao Badiganti 7a0440afc6 libpayload: Enable PCIe driver for sc7280
Enable PCIe driver for herobrine board.

BUG=b:182963902,b:216686574,b:181098581
TEST=Verified on Qualcomm sc7280 development board with NVMe card
(Koixa NVMe, Model-KBG40ZPZ256G with FW AEGA0102). Confirmed NVMe is
getting detected in response to 'storage init' command in depthcharge
CLI prompt.

Output logs:
  ->dpch: storage init
    Initializing NVMe controller 1e0f:0001
    Identified NVMe model KBG40ZPZ256G TOSHIBA MEMORY
    Added NVMe drive "NVMe Namespace 1" lbasize:512, count:0x1dcf32b0
    *  0: NVMe Namespace 1
    1 devices total

Also verified NVMe boot path, that is depthcharge is able to load the
kernel image from NVMe storage.

libpayload README
-------------------------------------------------------------------------------

libpayload is a minimal library to support standalone payloads
that can be booted with firmware like coreboot. It handles the setup
code, and provides common C library symbols such as malloc() and printf().

Note: This is _not_ a standard library for use with an operating system,
rather it's only useful for coreboot payload development!
See https://www.coreboot.org for details on coreboot.


Installation
------------

 $ git clone https://review.coreboot.org/coreboot.git

 $ cd coreboot/payloads/libpayload

 $ make menuconfig

 $ make

 $ make install (optional, will install into ./install per default)

On x86 systems, libpayload will always be 32-bit even if your host OS runs
in 64-bit, so you might have to install the 32-bit libgcc version.
On Debian systems you'd do 'apt-get install gcc-multilib' for example.

Run 'make distclean' before switching boards. This command will remove
your current .config file, so you need 'make menuconfig' again or
'make defconfig' in order to set up configuration. Default configuration
is based on 'configs/defconfig'. See the configs/ directory for examples
of configuration.


Usage
-----

Here's an example of a very simple payload (hello.c) and how to build it:

 #include <libpayload.h>

 int main(void)
 {
     printf("Hello, world!\n");
     return 0;
 }

Building the payload using the 'lpgcc' compiler wrapper:

 $ lpgcc -o hello.elf hello.c

Please see the sample/ directory for details.


Website and Mailing List

The main website is https://www.coreboot.org/Libpayload.

coreboot mailing list at https://www.coreboot.org/Mailinglist, where most
libpayload developers are subscribed.
