https://git.ethernal.org/mjb/altos/atom?h=debian%2F1.3-12013-12-19T08:08:50+00:00altos/lpc: Stop sending SETUP IN when the requested size is reached2013-12-19T08:08:50+00:00Keith Packardkeithp@keithp.com2013-12-19T08:08:50+00:00urn:sha1:a04c1dd5df76c9127615bc797a9d9f764eec1234
The host won't keep asking for SETUP IN packets once it has received
the amount of data requested, so check to see if we've sent that much
and flip back to IDLE state if so.

altos/lpc: Reset less of the device on USB reset.2013-12-19T07:27:34+00:00Keith Packardkeithp@keithp.com2013-12-19T07:27:34+00:00urn:sha1:1ab12861c3e70d7c22b27d988546a925616a0adc
This leaves most of the device configured across USB reset, which
appears to help when sending a IN reply to the first SETUP packet;
without this change, the IN reply would always get a length of 0,
which is fine for SET_ADDRESS, but not for GET_DESCRIPTOR_DEVICE,
which OS X appears to send before setting the address (go figure).

altos: Use all 16 bits of setup packet len when limiting reply len2013-12-18T07:53:59+00:00Keith Packardkeithp@keithp.com2013-12-18T07:50:54+00:00urn:sha1:1f035ac2df1cfa6964ae904aba0aedde279ca921
We were only using the low 8 bits of the setup packet reply max len,
which meant that if the other side sent a weird max len (as Windows 7
does), then we'd truncate our setup reply to whatever was in the low 8
bits of that value.

Support the USB boot loader, add USB pull-up support.

This involved carefully moving the USB away from the IRC before
turning it off.

altos/lpc: Force idle mode if USB gets an address during boot time2013-05-20T03:39:19+00:00Keith Packardkeithp@keithp.com2013-05-20T03:27:53+00:00urn:sha1:35b120c4154df0351c3a802f86dda224a7643068
This lets EasyMini be booted to idle mode by simply plugging it into USB.

altos/lpc: Don't use loader to place USB endpoint data in USB ram2013-05-20T03:39:18+00:00Keith Packardkeithp@keithp.com2013-05-20T03:06:03+00:00urn:sha1:6343bd774f542a4f915cf1fca2053d03e93bf2c3
Instead, just assign a fixed address in registers.ld. This avoids a
confusing section in the elf file.

No reason to have that in regular ram, and it means we've got space
for large enough stacks now

The lpc demo now has a USB command line.
Also allocates system stack so we know when ram is tight at build time
