基于ecos的redboot

2001-02-28  Hugo Tyson  <[e-mail]>

	* tests/pci1.c (pci_scan): Added a new function to re-scan the
	device list after configuring to let a human confirm that we truly
	are seeing distinct devices - ie. do they retain their distinct
	resource allocations in the BARs?  This was useful to me in
	investigating a recalcitrant target...

2001-02-02  Jesper Skov  <[e-mail]>

	* tests/pci2.c (pci_test): Removed bogus check for 1MB IO limit.

2001-01-10  Jesper Skov  <[e-mail]>

	* src/pci.c (cyg_pci_get_device_info): Do correct casting of
	header_type. Do not make assumptions about structure layout.

	* tests/pcihdr.h: Updated.

2001-01-02  Hugo Tyson  <[e-mail]>

	* include/pci.h: Define new API to perform more generalized matching
	on device properties.

	* src/pci.c (cyg_pci_find_matching): New API implementation.

2000-12-21  Mark Salter  <[e-mail]>

	* include/pci_hw.h: Add platform hook so certain devices
	can be skipped by generic PCI io code. This is a workaround
	for a hw problem where configuration space cycles on some
	devices cause a bus lockup.
	
	* src/pci.c (cyg_pci_find_next): Use platform hook to ignore
	certain devices during device search.

2000-12-02  Gary Thomas  <[e-mail]>

	* src/pci.c: 
	* cdl/io_pci.cdl: Add CDL to control debug prints.

2000-11-30  Gary Thomas  <[e-mail]>

	* src/pci.c (cyg_pci_find_next): Improve debug prints when
	scanning the bus, showing vendor and device code for each slot.

2000-11-19  Gary Thomas  <[e-mail]>

	* src/pci.c (cyg_pci_find_device): Don't update 'devid' if no
	suitable devices found.  This allows for simpler rescan for
	multiple device types.

2000-11-12  Gary Thomas  <[e-mail]>

	* src/pci_hw.c: 
	* src/pci.c: Layout changes require <pkgconf/hal.h>

	already configured devices.

	combined with CYG_PCI_NULL_DEVFN.
	(cyg_pci_configure_device): Return true if device already configured.
	Fixed for devices which use no BARs.
	(cyg_pci_allocate_io_priv): Remove bogus limit check.
	(cyg_pci_configure_bus): New function to recursively configure a
	bus and its subordinate bases.

	* include/pci_cfg.h: Added bridge definitions.
	(CYG_PCI_CFG_BAR_5): Corrected.

	* include/pci.h (CYG_PCI_NULL_DEVFN): Define.
	(cyg_pci_device): Add bridge support. Add num_bars. Add
	declaration for cyg_pci_configure_bus.
	(CYG_PCI_MAX_BUS): Increase to (arbitrary) 8.

	lacking same, also tidied up other typos as noticed en passant.

1999-12-21  Jonathan Larmour  <[e-mail]>

1999-09-10  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/io_pci.h: Reparent under CYGPKG_IO - this is used under
	more than one target now and the library itself is generic.
