2014-08-05libpayload: Change CONFIG_* to CONFIG_LP_* in the kconfig.Gabe Black
When libpayload header files are included in the payload itself, it's possible that the payloads config settings will conflict with the ones in libpayload. It's also possible for the libpayload config settings to conflict with the payloads. To avoid that, the libpayload config settings have _LP_ (for libpayload) added to them. The symbols themselves as defined in the Config.in files are still the same, but the prefix added to them is now CONFIG_LP_ instead of just CONFIG_.

2014-02-15libpayload/ahci: Fix a warning by decompartmentalise the AHCI driver.Edward O'Callaghan
Decompartmentalise AHCI driver into two parts, ATA and ATAPI. Add a few superficial comments while here. This also fixes a compiler warning.

2013-06-18libpayload: ahci: Increase timeout for signature readingNico Huber
We can't read the drives signature before it's ready, i.e. spun up. So set the timeout to the standard 30s. Also put a notice on the console, so the user knows why the signature reading failed.

2013-06-17libpayload: ahci: Fix command engine shutdownNico Huber
A timeout while waiting for a device' signature has shown that our error path wasn't correct. The shutdown of the ports command engine always timed out. Fix that by waiting for FR (FIS Receive Running) to be cleared independently from CR (Command List Running) and after clearing FRE (FIS Receive Enable).

Add the Mobile Panther Point (PPT) AHCI controller (DEVID 0x1e03) to the list of tested controllers. Also comment the only other listed controller (Mobile ICH9). The PPT AHCI controller was tested with a QM77 chipset on a Kontron KTQM77 board.

2012-10-27libpayload: New AHCI, ATA and ATAPI driversNico Huber
This adds a new interface for storage devices. A driver for ATA and ATAPI drives on AHCI host controllers comes along. The interface is very simple and was designed to match FILO's needs. It consists of three functions: void storage_initialize(void); Initializes controllers. Should be called once at startup. storage_poll_t storage_probe(size_t dev_num); with typedef enum { POLL_NO_DEVICE = -2, POLL_ERROR = -1, POLL_NO_MEDIUM = 0, POLL_MEDIUM_PRESENT = 1, } storage_poll_t; Looks for a drive with number dev_num (drives are counted from zero) and polls for a medium in the drive if appropriate. int storage_read_blocks512(size_t dev_num, u64 start, size_t count, unsigned char *buf); Reads count blocks of 512 bytes from block start of drive dev_num into buf.
