Este é um cabeçalho bagulhão que uso faz tempo, em especial quando uso o GCC mas até pra ajudar na portabilidade pra outros compiladores, uso não apenas em programas embarcados, por isto tem um coisas demais:

Este aqui de baixo é o pstdint.h (de "portable stdint.h"), em especial para compiladores que fogem do padrão ISO C 99. Fiz apenas umas duas ou três alterações para compatibilidade com o outro cabeçalho acima (se lembro bem, sei que tinha algo errado).
Como existe esta confusão entre vendors de compiladores quanto aos inteiros, com nomenclaturas como u8,u16 ou int8 ou int16, ou por aí vai, resolvi adotar o formato intX_t ou uintX_t (onde x é o tamanho em bits), que é reconhecido em vários standards, alguns bem anteriores ao ISO C 9x. Só uso opções "a la carte" se não existir um padrão razoável hehe.

*
* Version 0.1.10
*
* The ANSI C standard committee, for the C99 standard, specified the
* inclusion of a new standard include file called stdint.h. This is
* a very useful and long desired include file which contains several
* very precise definitions for integer scalar types that is
* critically important for making portable several classes of
* applications including cryptography, hashing, variable length
* integer libraries and so on. But for most developers its likely
* useful just for programming sanity.
*
* The problem is that most compiler vendors have decided not to
* implement the C99 standard, and the next C++ language standard
* (which has a lot more mindshare these days) will be a long time in
* coming and its unknown whether or not it will include stdint.h or
* how much adoption it will have. Either way, it will be a long time
* before all compilers come with a stdint.h and it also does nothing
* for the extremely large number of compilers available today which
* do not include this file, or anything comparable to it.
*
* So that's what this file is all about. Its an attempt to build a
* single universal include file that works on as many platforms as
* possible to deliver what stdint.h is supposed to. A few things
* that should be noted about this file:
*
* 1) It is not guaranteed to be portable and/or present an identical
* interface on all platforms. The extreme variability of the
* ANSI C standard makes this an impossibility right from the
* very get go. Its really only meant to be useful for the vast
* majority of platforms that possess the capability of
* implementing usefully and precisely defined, standard sized
* integer scalars. Systems which are not intrinsically 2s
* complement may produce invalid constants.
*
* 2) There is an unavoidable use of non-reserved symbols.
*
* 3) Other standard include files are invoked.
*
* 4) This file may come in conflict with future platforms that do
* include stdint.h. The hope is that one or the other can be
* used with no real difference.
*
* 5) In the current verison, if your platform can't represent
* int32_t, int16_t and int8_t, it just dumps out with a compiler
* error.
*
* 6) 64 bit integers may or may not be defined. Test for their
* presence with the test: #ifdef INT64_MAX or #ifdef UINT64_MAX.
* Note that this is different from the C99 specification which
* requires the existence of 64 bit support in the compiler. If
* this is not defined for your platform, yet it is capable of
* dealing with 64 bits then it is because this file has not yet
* been extended to cover all of your system's capabilities.
*
* 7) (u)intptr_t may or may not be defined. Test for its presence
* with the test: #ifdef PTRDIFF_MAX. If this is not defined
* for your platform, then it is because this file has not yet
* been extended to cover all of your system's capabilities, not
* because its optional.
*
* 8) The following might not been defined even if your platform is
* capable of defining it:
*
* WCHAR_MIN
* WCHAR_MAX
* (u)int64_t
* PTRDIFF_MIN
* PTRDIFF_MAX
* (u)intptr_t
*
* 9) The following have not been defined:
*
* WINT_MIN
* WINT_MAX
*
* 10) The criteria for defining (u)int_least(*)_t isn't clear,
* except for systems which don't have a type that precisely
* defined 8, 16, or 32 bit types (which this include file does
* not support anyways). Default definitions have been given.
*
* 11) The criteria for defining (u)int_fast(*)_t isn't something I
* would trust to any particular compiler vendor or the ANSI C
* committee. It is well known that "compatible systems" are
* commonly created that have very different performance
* characteristics from the systems they are compatible with,
* especially those whose vendors make both the compiler and the
* system. Default definitions have been given, but its strongly
* recommended that users never use these definitions for any
* reason (they do *NOT* deliver any serious guarantee of
* improved performance -- not in this file, nor any vendor's
* stdint.h).
*
* 12) The following macros:
*
* PRINTF_INTMAX_MODIFIER
* PRINTF_INT64_MODIFIER
* PRINTF_INT32_MODIFIER
* PRINTF_INT16_MODIFIER
* PRINTF_LEAST64_MODIFIER
* PRINTF_LEAST32_MODIFIER
* PRINTF_LEAST16_MODIFIER
* PRINTF_INTPTR_MODIFIER
*
* are strings which have been defined as the modifiers required
* for the "d", "u" and "x" printf formats to correctly output
* (u)intmax_t, (u)int64_t, (u)int32_t, (u)int16_t, (u)least64_t,
* (u)least32_t, (u)least16_t and (u)intptr_t types respectively.
* PRINTF_INTPTR_MODIFIER is not defined for some systems which
* provide their own stdint.h. PRINTF_INT64_MODIFIER is not
* defined if INT64_MAX is not defined. These are an extension
* beyond what C99 specifies must be in stdint.h.
*
* In addition, the following macros are defined:
*
* PRINTF_INTMAX_HEX_WIDTH
* PRINTF_INT64_HEX_WIDTH
* PRINTF_INT32_HEX_WIDTH
* PRINTF_INT16_HEX_WIDTH
* PRINTF_INT8_HEX_WIDTH
* PRINTF_INTMAX_DEC_WIDTH
* PRINTF_INT64_DEC_WIDTH
* PRINTF_INT32_DEC_WIDTH
* PRINTF_INT16_DEC_WIDTH
* PRINTF_INT8_DEC_WIDTH
*
* Which specifies the maximum number of characters required to
* print the number of that type in either hexadecimal or decimal.
* These are an extension beyond what C99 specifies must be in
* stdint.h.
*
* Compilers tested (all with 0 warnings at their highest respective
* settings): Borland Turbo C 2.0, WATCOM C/C++ 11.0 (16 bits and 32
* bits), Microsoft Visual C++ 6.0 (32 bit), Microsoft Visual Studio
* .net (VC7), Intel C++ 4.0, GNU gcc v3.3.3
*
* This file should be considered a work in progress. Suggestions for
* improvements, especially those which increase coverage are strongly
* encouraged.
*
* Acknowledgements

* The following people have made significant contributions to the
* development and testing of this file:

Ai quanto a seleção de placas e etc, como você está fazendo, eu não avancei muito, no máximo fiz isto aqui:
- Código: Selecionar todos

Eu só usei este modelo aí pra coisas inúteis, nos projetos que acabei tocando em cima de ARM, devido a restrições de tempo e preguiça (e outra desculpas esfarrapadas) no máximo fiz um cabeçalho pra cada um com definições de pinos e outras coisas, sem ter padrão nenhum.
Mas é bacana trocar figurinhas a respeito, se eu criar coragem adoto um padrão mínimo hehe.
Boa sorte, vai postando tuas idéias aí que são bem vindas!
Não há possibilidade de se criar uma BIOS a semelhança do IBM PC ?
