Rename (AMD64|I386)_BUS_SPACE_* to X86_BUS_SPACE_* everywhere. Reviewed by: imp (previous version), jhb Approved by: kib (mentor) Use bus_space_compare() rather than i386_memio_compare() directly. 2008-09-07T04:47:39Z Yoshihiro Takahashi nyan@FreeBSD.org 2008-09-07T04:47:39Z urn:sha1:3726c6bbc1018b1859db65917cea7c20d76ca807 Add the 2nd CCU and PnP devices support on pc98. 2008-08-25T14:45:24Z Yoshihiro Takahashi nyan@FreeBSD.org 2008-08-25T14:45:24Z urn:sha1:81df65c3112c0e384eaa2ed99f4df8d2830c0d85 Reviewed by: imp Obtained from: //depot/projects/uart with some fixes Don't expose the uart_ops structure directly, but instead have 2007-04-02T22:00:22Z Marcel Moolenaar marcel@FreeBSD.org 2007-04-02T22:00:22Z urn:sha1:f8100ce2a70db5c60672578fee913d986ac1cf01 it obtained through the uart_class structure. This allows us to declare the uart_class structure as weak and as such allows us to reference it even when it's not compiled-in. It also allows is to get the uart_ops structure by name, which makes it possible to implement the dt tag handling in uart_getenv(). The side-effect of all this is that we're using the uart_class structure more consistently which means that we now also have access to the size of the bus space block needed by the hardware when we map the bus space, eliminating any hardcoding. Make uart_getenv() not be ns8250 dependent. This will allow, in the future, 2005-12-12T21:00:58Z Warner Losh imp@FreeBSD.org 2005-12-12T21:00:58Z urn:sha1:fbd68c4b4ce9f404df4a819e64680f29bf0c7cce compilation of kernels without ns8250 support but using the uart framework.

Expect for sparc64 these are only stubs right now. [1] - For sparc64, add code to its uart_cpu_identify() for registering the on- board ISA UARTs and their resources based on information obtained from Open Firmware. It would be better if this would be done in the OFW ISA code. However, due to the common FreeBSD ISA code and PNP-IDs not always being present in the properties of the ISA nodes there seems to be no good way to implement that. Therefore special casing UARTs as the sole really relevant ISA devices on sparc64 seemed reasonable.
