From dbec2d4090e40d1d8e1fd06e8d4180d3fa685d4d Mon Sep 17 00:00:00 2001 From: Eric Biederman Date: Thu, 21 Oct 2004 10:44:08 +0000 Subject: - Bump the LinuxBIOS major version - Rename chip_config chip_operations throughout the tree - Fix Config.lb on most of the Opteron Ports - Fix the amd 8000 chipset support for setting the subsystem vendor and device ids - Add detection of devices that are on the motherboard (i.e. In Config.lb) - Baby step in getting the resource limit handling correct, Ignore fixed resources - Only call enable_childrens_resources on devices we know will have children For some busses like i2c it is non-sense and we don't want it. - Set the resource limits for pnp devices resources. - Improve the resource size detection for pnp devices. - Added a configuration register to amd8111_ide.c so we can enable/disable individual ide channels - Added a header file to hold the prototype of isa_dma_init - Fixed most of the superio chips so the should work now, the via superio pci device is the exception. - The code compiles and runs so it is time for me to go to bed. git-svn-id: svn://svn.coreboot.org/coreboot/trunk@1698 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1 --- src/superio/NSC/pc97307/chip.h | 8 +++- src/superio/NSC/pc97307/pc97307.h | 10 +++++ src/superio/NSC/pc97307/superio.c | 93 ++++++++++++++++++++++++--------------- 3 files changed, 73 insertions(+), 38 deletions(-) create mode 100644 src/superio/NSC/pc97307/pc97307.h (limited to 'src/superio/NSC/pc97307') diff --git a/src/superio/NSC/pc97307/chip.h b/src/superio/NSC/pc97307/chip.h index fd78e8e89f..369c47a44b 100644 --- a/src/superio/NSC/pc97307/chip.h +++ b/src/superio/NSC/pc97307/chip.h @@ -14,9 +14,13 @@ #define SIO_COM2_BASE 0x2F8 #endif -extern struct chip_control superio_NSC_pc97307_control; +extern struct chip_operations superio_NSC_pc97307_control; + +#include +#include struct superio_NSC_pc97307_config { - int port; + struct uart8250 com1, com2; + struct pc_keyboard keyboard; }; #endif /* _SUPERIO_NSC_PC97307 */ diff --git a/src/superio/NSC/pc97307/pc97307.h b/src/superio/NSC/pc97307/pc97307.h new file mode 100644 index 0000000000..fa1f7f69b5 --- /dev/null +++ b/src/superio/NSC/pc97307/pc97307.h @@ -0,0 +1,10 @@ +#define PC97307_KBCK 0x00 /* Keyboard */ +#define PC97307_KBCM 0x01 /* Mouse */ +#define PC97307_RTC 0x02 /* Real-Time Clock */ +#define PC97307_FDC 0x03 /* Floppy */ +#define PC97307_PP 0x04 /* Parallel port */ +#define PC97307_SP2 0x05 /* Com2 */ +#define PC97307_SP1 0x06 /* Com1 */ +#define PC97307_GPIO 0x07 +#define PC97307_PM 0x08 /* Power Management */ + diff --git a/src/superio/NSC/pc97307/superio.c b/src/superio/NSC/pc97307/superio.c index 2fb62e1c93..a0732d05f2 100644 --- a/src/superio/NSC/pc97307/superio.c +++ b/src/superio/NSC/pc97307/superio.c @@ -4,44 +4,41 @@ #include #include #include "chip.h" +#include "pc97307.h" -void pnp_output(char address, char data) -{ - outb(address, PNP_CFGADDR); - outb(data, PNP_CFGDATA); -} - -void sio_enable(struct chip *chip, enum chip_pass pass) +static void init(device_t dev) { + struct superio_NSC_pc97307_config *conf; + struct resource *res0, *res1; - unsigned char reg; + if (!dev->enabled) { + return; + } + conf = dev->chip; + switch(dev->path.u.pnp.device) { + case PC97307_SP1: + res0 = find_resource(dev, PNP_IDX_IO0); + init_uart8250(res0->base, &conf->com1); + break; - switch (pass) { - case CONF_PASS_PRE_PCI: - printk_info("Configuring PC97307...\n"); + case PC97307_SP2: + res0 = find_resource(dev, PNP_IDX_IO0); + init_uart8250(res0->base, &conf->com2); + break; + case PC97307_KBCK: /* Enable keyboard */ - pnp_output(0x07, 0x00); - pnp_output(0x30, 0x00); /* Disable keyboard */ - pnp_output(0xf0, 0x40); /* Set KBC clock to 8 Mhz */ - pnp_output(0x30, 0x01); /* Enable keyboard */ - - /* Enable mouse */ - pnp_output(0x07, 0x01); - pnp_output(0x30, 0x01); - - /* Enable rtc */ - pnp_output(0x07, 0x02); - pnp_output(0x30, 0x01); + pnp_set_logical_device(dev); + pnp_set_enable(dev, 0); /* Disable keyboard */ + pnp_write_config(dev, 0xf0, 0x40); /* Set KBC clock to 8 Mhz */ + pnp_set_enable(dev, 1); /* Enable keyboard */ - /* Enable fdc */ - pnp_output(0x07, 0x03); - pnp_output(0x30, 0x01); - - /* Enable parallel port */ - pnp_output(0x07, 0x04); - pnp_output(0x30, 0x01); + res0 = find_resource(dev, PNP_IDX_IO0); + res1 = find_resource(dev, PNP_IDX_IO1); + init_pc_keyboard(res0->base, res1->base, &conf->keyboard); + break; + case PC97307_FDC: /* Set up floppy in PS/2 mode */ outb(0x09, SIO_CONFIG_RA); reg = inb(SIO_CONFIG_RD); @@ -49,13 +46,37 @@ void sio_enable(struct chip *chip, enum chip_pass pass) outb(reg, SIO_CONFIG_RD); outb(reg, SIO_CONFIG_RD); /* Have to write twice to change!
