Some xHCI controller's reset time than 100ms,such as 120ms. On the on hand, xHCI spec has not specified a timeout value. Maybe setting xHCI HCRST and CNR bit clear timeout value larger is a nice thing.As a compromise between compatibility and latency,we can take 1000ms as a timeout value.

2020-09-25usb.c: Fix devices using non-primary interface descriptorMatt DeVillier1-8/+19
A fair number of USB devices (keyboards in particular) use an interface descriptor other than the first available, making them non-functional currently. To correct this, iterate through all available interface descriptors until one with the correct class/subclass is found, then proceed to set the configuration and setup the driver.

2020-09-08smbios: avoid integer overflow when adding SMBIOS type 0 tableDaniel P. Berrangé1-4/+10
SeaBIOS implements the SMBIOS 2.1 entry point which is limited to a maximum length of 0xffff. If the SMBIOS data received from QEMU is large enough, then adding the type 0 table will cause integer overflow. This results in fun behaviour such as KVM crash, or hangs in SeaBIOS.

2020-06-26timer: Handle decrements of PIT counterRoman Bolshakov1-1/+1
There's a fallback to PIT if TSC is not present but it doesn't work properly. It prevents boot from floppy on isapc and 486 cpu [1][2]. SeaBIOS configures PIT in Mode 2. PIT counter is decremented in the mode but timer_adjust_bits() thinks that the counter overflows and increases 32-bit tick counter on each detected "overflow". Invalid overflow detection results in 55ms time advance (1 / 18.2Hz) on each read from PIT counter. So all timers expire much faster and 5-second floppy timeout expires in 83 real microseconds (or just a bit longer). It can be fixed by making the counter recieved from PIT an increasing value so it can be passed to timer_adjust_bits(): 0, 1, 2 and up to 65535 and then the counter is re-loaded with 0. 1. https://bugs.launchpad.net/seabios/+bug/1840719 2. https://lists.gnu.org/archive/html/qemu-devel/2019-08/msg03924.html Fixes: eac11944019 ("Unify pmtimer_read() and pittimer_read() code.")

R. Silva <gustavo@embeddedor.com> from his Linux kernel commits.] The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member [1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.
