2003-09-21 Jonathan Larmour <jifl@eCosCentric.com> * src/var_misc.c (hal_variant_init): Set FPSCR on startup. * src/sh4_scif.c (cyg_hal_plf_scif_set_baud): New function, taken from init code, but with fix to wait for hardware to settle. (cyg_hal_plf_scif_control): Add __COMMCTL_GETBAUD and _SETBAUD support using above function. * include/sh4_scif.h: Add baud_rate to channel data. * include/mod_regs_ser.h (CYGARC_SCBRR_N): Don't tweak BRR for values < 4800 or > 115200 as it gets the values wrong. Instead trust the developer to DTRT. (CYGARC_REG_SCIF_SCLSR_ORER): Add definition for overrun in line status reg. 2003-09-19 John Dallaway <jld@ecoscentric.com> * cdl/hal_sh_sh4.cdl: Specify default CDL values for sh4_202_md target. 2003-09-11 Nick Garnett <nickg@ecoscentric.com> * include/var_regs.h (CYG_FPSCR): Changed initial value of fpscr to do round-to-nearest rather than round-to-zero. 2003-09-08 Nick Garnett <nickg@ecoscentric.com> * include/mod_202.h: Added define for UBC. The 202 appears to have one, although there is no documented info. It is also not clear what version it is. Setting this to 1 seems to work. * include/mod_regs_cac.h: * include/variant.inc: Updated cache dimensions and initialization to support larger, two way cache in sh4-202. 2003-09-05 Nick Garnett <nickg@ecoscentric.com> * include/variant.inc: * include/var_reg.h: * include/mod_202.h: * include/mod_regs_cpg.h: * include/mod_regs_emi.h: * include/mod_regs_femi.h: * include/mod_regs_intc.h: * cdl/hal_sh_sh4.cdl: Added SH-202 sub-variant, extra functional units, and modifications to existing units for this variant.
