Sean Cross 014c950580 remote: usb: print "access denied" error
When we get an error with errno 13, it means that the user doesn't
have access to the USB device.  Rather than silently eating this
error and returning -1, print out a message to aid in debugging.

Sean Cross faf6554c89 remote: usb: use 0x43/0xc3 for packet header
The previous value -- 0xc0 -- is used by Windows all the time to query
special descriptors.  This was causing a conflict when using the USB
bridge on a Windows device.

Change the magic packet from "Vendor: Device" queries to "Vendor:
Other" by setting the bottom two bits.

Gabriel L. Somlo 5707bdc0a4 boards/nexys4ddr: ethernet support fix-up
Commit 5f6e7874 added ethernet support, let's now also expose it via
the "--with-ethernet" command line argument.

Florent Kermarrec 526ba1b165 soc_core: remove csr_expose and add add_csr_master method
This could be useful in specific case were we don't have a wishbone master
but just want to have a csr bus and allow the user to define it.

/!\ Since there is no arbitration on between the CSR masters, use this with
precaution /!\

Florent Kermarrec 67159349d6 soc/interconnect: remove axi_lite
axi_lite code was defining AXI4Lite signals and doing a AXI4Lite bridge to the
CSR bus when LiteX was not having proper AXI support. LiteX now has  proper AXI
support and it also cover what axi_lite was doing: To create a AXILite to CSR
bus, user can create an AXILite2Wishbone bridge and then connect the CSR bus
directly to the wishbone bus as done in the others non-AXI SoC.

Florent Kermarrec 47dc87584f integration/soc_core: rework interrupt assignation/reservation
The CPUs can now reserve specific interrupts with reserved_interrupts property.
User can still define interrupts in SoCCore.interrupt_map (old way) or use
add_interrupt method. Interrupts specific to SoCCore internal modules are
allocated automatically on the remaining free interrupt ids.

Priority for the interrupts allocation:
- 1) CPU reserved interrupts.
- 2) User interrupts.
- 3) SoCCore interrupts.

soc/integration/cpu_interface: more arch-specific address size fixes
2019-05-09 08:57:31 +02:00
Gabriel L. Somlo c264a00964 soc/integration/cpu_interface: more arch-specific address size fixes
When generating arch-specific include files (generated/[mem|csr].h)
ensure address literal defines are suffixed by 'L', denoting their
'unsigned long' type. This inhibits compiler warnings when values
computed based on these constants are cast to pointers.

Also ensure csr_[read|write][b|w|l]() function declarations have
'unsigned long' address arguments.

Finally, restore the correct (32-bit, (unsigned *)) expected
behavior of the MMPTR() macro, inadvertently converted to an
arch-specific sized access (unsigned long *) by commit 5c2b8685.
