call usbcreate_disk. This is inappropriate because it forms
a 1:1 mapping of USB device to disk leading to the inability
to remove the disk and/or handle "hot plug" card insertion
and removals.
To alleviate this issue introduce the notion of ready to the
usbmsc structure. It tracks detached, not ready, and ready
states. The polling routine is then used to track not ready
to ready transitions thereby creating and removing disks
appropriately. This handles the case of inserting and removing

xHCI requires special treatment of set_address since it determines
the device number itself (instead of the driver, as with the other
controllers). The controller also wants to validate a chosen device
configuration and we need to setup additional structures for the
device and the endpoints.
Therefore, we add three functions to the hci_t structure, namely:
set_address()
finish_device_config()
destroy_device()
Current implementation for the Set Address request moved into
generic_set_address() which is set_address() for the UHCI, OCHI and
EHCI drivers. The latter two are only provided as hooks for the xHCI
driver.
The Set Configuration request is moved after endpoint enumeration.
For all other controller drivers nothing changes, as there is no other
device communication between the lines where the set_configuration()
call moved.

It might be useful to provide a USB driver in the payload itself instead of in
libpayload. For example there are multiple payloads being built and linked
against the same libpayload, and they might not need or even want to have the
same set of drivers installed.
This change adds two new functions, usb_generic_create and usb_generic_remove,
which behave like the usbdisk_create and usbdisk_remove functions which are
defined for USB mass storage devices. If a USB device isn't recognized and
claimed by one of the built in USB class drivers (currently hub, hid, and msc)
and the create function is defined, then it will be called to give the payload
a chance to use the device. Once it's removed, if usb_generic_remove is
defined it will be called, effectively giving the payload notice.
Built and booted depthcharge on Link. Built depthcharge for Daisy. Built
a netbooting payload, called usb_poll() with those functions implemented, and
verified that they were called and that the devices they were told about were

There weren't enough parenthesis in the macros so operations might only apply
to the last part of an expression passed in as an argument.

The functions in endian.h (betoh{l,w,ll} and others) were named differently from
the well-known BSD/glibc style endian functions (ex, betoh{16,32,64}). We should
provide the BSD/glibc style functions to prevent confusion.

Give some indication what happened instead of just crashing.
As part of setup, cause an exception and make sure that we get
the right one, and that we recover correctly. Hence we have
some assurance that if they really happen we can handle them.
Built and booted into test payload on Snow. Saw the built in test function
worked correctly. Artificially added code which got an exception and saw that
the error information prints correctly.

This is so the user of libpayload can attach data to the device which it can
retrieve when the device is referred to later, for instance in usbdisk_remove.
Otherwise, there's no direct connection from the usbdev_t structure to any
bookkeeping in the host firmware.

The compiler gets mad when the types are equivalent size but not necessarily
interchangeable because of strict aliasing checks. Since uint32_t is likely to
be used when trying to read 32 bit data, it makes sense for them to be the
compatible.

Upgrade CBFS in libpayload to use new media-based implementation from coreboot
( http://review.coreboot.org/#/c/2182/ ).
Old CBFS functions (cbfs_find, cbfs_find_file, get_cbfs_header) are still
supported, although the recommended way is to use new CBFS API.
To migrate your existing x86 payload source:
- Change cbfs_find to cbfs_get_file
- Change cbfs_find_file to cbfs_get_file_content
- Prefix every CBFS call with a CBFS_DEFAULT_MEDIA argument.
Ex, char *jpeg_data = cbfs_find_file("splash.jpg", CBFS_TYPE_BOOTSPLASH);
=> char *jpeg_data = cbfs_get_file_content(
CBFS_DEFAULT_MEDIA, "splash.jpg", CBFS_TYPE_BOOTSPLASH);
The legacy setup_cbfs_from_{ram,flash} is also supported, although the better
equivalent is to make a new media instance:
struct cbfs_media ram_media;
init_cbfs_ram_media(&ram_media, start, size);
char *data = cbfs_get_file_content(&ram_media, "myfile", my_type);
Verified by being successfully linked with filo.
